WHAT: FLEET & MCATM Seminar: Professor Jennifer Hoffman - Imaging the surface states of a strongly correlated topological insulator
WHERE: Seminar Room 107, 10 College Walk, Monash Clayton

Seminar Flyer can be downloaded here. All welcome.

Abstract: The prediction and subsequent discovery of topological band insulators with robust spin-polarized surface states has launched a new subfield of physics over the last decade.

In the last few years it has been recognized that when topology is combined with strong electron-electron correlations, even more interesting and potentially useful states of matter can arise, such as new topological classifications, fractionalized states, and many-body localization that preserves the topology of the insulating state against thermal destruction.

This seminar gives a general introduction to topological materials, and show the first direct proof of a strongly correlated topological insulator.

About the Speaker: Professor Jenny Hoffman is interested in how electrons behave within exotic materials. Her research team at Harvard has designed and constructed three low-temperature scanning probe microscopes to visualize and manipulate this behavior directly.

Innovative techniques include quasiparticle interference imaging to extract the band structure of materials at the nanoscale, and force microscopy to trigger nanoscale electronic phase transitions. Materials of particular interest include high temperature superconductors, topological insulators, and strongly correlated vanadates, all of which present deep physics questions as well as potential for novel applications.

WHEN: 24 July 2017, 11AM
WHAT: Seminar co-hosted by Materials Science & Engineering and MCATM: Liming Dai - Functional Energy Materials: From 1D and 2D Polymers to 3D Carbon Nanomaterials
WHERE: S14 Lecture Theatre, 11 Rainforest Walk, Monash Clayton

Seminar Flyer can be downloaded here. All welcome.

Abstract: Polymers have been traditionally used as electrically insulating materials: after all, metal wires are coated in plastics to insulate them. However, various conjugated macromolecules with alternating single and double bonds have been synthesized with unusual electrical and optical properties through the pi-electron delocalization along their 1D backbones.

A number of synthetic methods have also been devised to produce conjugated polymers with the processing advantages of plastics and the optoelectronic properties of inorganic semiconductors for energy conversion and storage, including polymer photovoltaic cells. Having conjugated all-carbon structures, carbon nanomaterials, including 1D carbon nanotubes and 2D graphene, also possess certain similar optoelectronic characteristics as conjugated macromolecules. Thus, carbon nanomaterials (e.g., 1D carbon nanotubes, 2D graphene sheets, 3D carbon architectures) have been playing a more and more important role in the development of efficient energy conversion and storage devices.

In this talk, I will present some of our rational concepts for the design and development of functional conjugated polymers and multidimensional carbon nanomaterials for various energy-related applications, including polymer solar cells containing graphene nanosheets for improving charge transport, fuel cells and metal-air batteries with carbon nanomaterials as multifunctional metal-free catalysts, and supercapacitors with nanotube/graphene hybrid electrodes for energy storage.

WHEN: 21 July 2017, 11AM
WHAT: MCATM Seminar: Changgu Lee - Magnetic and Physical properties of new 2D materials
WHERE: 407 New Horizons Centre.

Seminar Flyer can be downloaded here. All welcome.

Abstract: The representative 2D materials, graphene, h-BN, and MoS2, have interesting mechanical, electrical and optical properties and have exhibited fascinating physical phenomena so far. However, they mostly lack one important physical property in physics, magnetism. The new 2D materials such as CrSiTe3, CrI3, and FePS3, which began to be studied recently, possess ferro- or antiferro-magentic properties even in atomic level thickness and are expected to reveal deep level of physics in 2-dimensional confinement.

In this talk, our recent works on thickness dependence of magnetic and optical properties of ternary 2D materials, Fe3GeTe2 and CrPS4, which are ferromagnetic and antiferromagnetic 2D materials, will be presented. Fe3GeTe2 was studied with hall measurement and STM methods. From the hall measurement, it exhibited the anomalous hall effect due to its intrinsic ferromagnetism. Interestingly, the magnetic properties such as coercivity changed significantly with decreasing thickness changing from weak ferromagnet to strong ferromagnet.

STM study revealed some magnetic domains on the surface. The domain structures barely changed below Curie temperature, but disappeared above the critical temperature, which suggests they are magnetic structures. CrPS4, which is an antiferromagnet, was characterized with Raman and PL spectroscopies. Its bandgap was measured to be roughly 1.3 eV and its structure showed strong in-plane optical anisotropy.

About the Speaker: A/Prof. Changgu Lee joined the department of Mechanical Engineering and SKKU Advanced Institute of Nanotechnology, Suwon, Korea in 2010 after his postdoctoral appointment at Columbia University, New York, USA working with Prof. James Hone.

Recent efforts in our group at reducing contact resistance to MoS2, selectively doping it to realize high performance lateral p-n junctions, and understanding the origins of hysteresis in MoS2 transistors will be discussed. Infrastructural and fabrication expertise relevant to 2D material characterization and device fabrication available in our research group will also be presented.

WHEN: 17 February 2017, 11AM
WHAT: MCATM Seminar: Chris McConville, RMIT University & University of Warwick "Unusual Electronic Structure of Transparent Conducting Oxide Semiconductors"
WHERE: G30 New Horizons Centre.

Seminar Flyer can be downloaded here. All welcome.

Abstract: Oxide semiconductors have become of great technological interest and importance in recent years with opportunities to improve both the existing materials and their potential device applications. This is particularly true for a sub-group of materials that display both optical transparency and high electrical conductivity, the so-called transparent conducting oxides (TCO’s).

The fact that some of these materials, such indium tin oxide (ITO) have been around for many years and seen significant industrial use as transparent conductors in a relatively low quality form, has perhaps contributed to the belated recognition of using these materials as semiconductors in their own right. Here, examples from the surface and bulk electronic properties of several epitaxially grown oxide semiconductors (In2O3, CdO and ZnO) will be discussed along with the effects of modifying their surfaces by controlled adsorption.

The valence band density of states and the surface electronic properties of these TCO’s have been studied using high-resolution synchrotron radiation angle-resolved photoemission (SR-ARPES) and core-level photoemission spectroscopy with hard x-rays (HAXPES), both at the Diamond Light Source, and    these data are compared with theoretical DFT band structure calculations. A common property of these oxide semiconductors is the presence of a significant electron accumulation layer at the surface.

While this is similar to that found at the surfaces of materials such as InN and In-rich InGaN, it is in marked contrast to the electron depletion typically observed at the surfaces of conventional III-V, II-VI and Group IV semiconductor materials. More unusual still is the quantized nature of this surface 2D electron gas. The origins of this phenomenon will be discussed in terms of the band structure and intrinsic properties of these materials.

WHEN: 31 January 2017, 11AM
WHAT: MCATM Seminar: Wanqin Jin - Design and Fabrication of Graphene-based Membranes for Molecular Separation
WHERE: Potter Room 222, Bld 36, 2nd floor of 18 Alliance Lane, Clayton Campus

Seminar Flyer can be downloaded here. All welcome.

Graphene and its derivatives (e.g., graphene oxide (GO)) have become emerging nano-building blocks for separation membranes featuring distinct laminar structures and tunable physicochemical properties. Extraordinary molecular separation properties for purifying water and gases have been demonstrated    by graphene-based membranes, which have attracted a huge surge of interest during the past few years.

However, most of the graphene-based membranes are polymeric supported or free-standing, whose practical application is limited due to the lack of mechanical strength and thermal and chemical stability. To address this problem, we demonstrated a scalable fabrication of GO membranes on ceramic hollow    fiber substrate and showed good PV dehydrotion of aqueous organic solution. Moreover, we demonstrated a novel bio-inspired strategy that utilizes the synergistic effect of a hydrophilic polymer and GO laminates to realize fast water-transport channels for constructing high-efficiency membrane.

For gas separation, we proposed a novel type of membrane with fast and selective gas-transport channels of GO laminates enabled by polymer-GO hydrogen bonding.The as-prepared GO-based membrane showed excellent CO2 permeation performance and extraordinary operational stability. Several strategies including    the facile spray-evaporation and integrated external forces driven assembly (EFDA) approaches were proposed to precisely manipulate the GO membranes with highly ordered 2D microstructure for precise molecular gas separation. Future efforts should be taken to further develop high-quality graphene and    other 2D materials membranes for efficient water desalination and enhance the membrane stability for practical application.

Two-dimensional (2D) materials have applications in low-power electronics and energy-conversion systems. These are also rich domains for both fundamental discoveries as well as technological advances. This talk will present recent highlights from our research on graphene, BN, and transition metal dichalcogenides    (TMDs). We have studied graphene from basic transport measurements and simulations, to the recent wafer-scale demonstration of analog dot product nanofunctions for neural networks.

We are also growing and evaluating the electrical, thermal, and thermoelectric properties of TMDs including MoS2, MoSe2, HfSe2, and WTe2. Recent results include low-resistance contacts, 10-nm scale transistors, and high-field transport studies including velocity saturation.

We have also examined the anisotropic thermal conductivity of these materials, for unconventional applications to thermal switches and thermal routing. If time permits, I will discuss “bottom up” thermal management starting at dimensions comparable to the electron and phonon mean free paths    (~100 nm), where quasi-ballistic heat flow effects dominate. Our studies reveal fundamental limits and new applications that could be achieved through the co-design and heterogeneous integration of 2D nanomaterials.

Abstract: Graphene materials have been attracting significant research interest owing to its huge specific surface area, large room-temperature electron mobility, excellent mechanical flexibility, exceptionally high thermal conductivity and environmental stability. As a result, graphene    is identified as a beneficial additive or an effective responsive component by itself to improve the conductivity, flexibility, mechanical strength and/or the overall responsive performance of smart devices and systems.

In this regard, we have demonstrated the versatile assembly of graphene into a variety of flexible structures and their energy-related devices in response to external stimulations, such as environmental variation. These smart stimulus responsive graphene energy systems are believed to have great theoretical    and practical interests to a wide range of applications.

WHAT: Epitaxial Graphene Naturally Enables Terahertz Optoelectronics
WHERE: G30 New Horizons Centre.

Seminar Flyer can be downloaded here. Seats are limited so please RSVP your attendance. All welcome.

Abstract: Large area, single crystal epitaxial graphene (EG) is attractive for optoelectronic applications ranging from many terahertz down to the sub-terahertz. Various structures such as quantum dots and micro ribbon arrays can be fabricated relatively easily on EG using standard    practices. We briefly describe using quantum dots as bolometers with responsivity five orders of magnitude higher than other types of graphene bolometers and extremely low electrical noise equivalent power at 2.5 K).

Graphene ribbons, the main focus of this presentation, have THz plasmonic resonances with frequencies dependent upon the graphene sheet density and the (subwavelength) patterned width and period. Radiation incident on these plasmonic structures give rise to a photothermal response which can be tuned    by gating and has characteristic response times < 100 ps. Additionally, anomalously high resonance absorption or transmission can be achieved by fabricating arrays of graphene apertures in an otherwise conducting layer. This creates an opportunity to make terahertz filters, oscillators, detectors    and modulators with good performance.

Recently, we have found that hydrogen intercalated EG, sometimes termed quasi-free standing graphene, results in mobility improvement by approx. 3-fold which gives rise to unprecedented narrow plasmonic resonances, implying the potential for high performance THz optoelectronics. In addition, improved    mobility should    translate into increased detection efficiency in the sub-terahertz domain using resonance enhanced field effect transistor or photothermoelectric detectors. We discuss the impact of such sensitive sub-terahertz detectors on potential radiometry/meteorology applications    that include aircraft safety.

WHAT: MCATM Seminar: Patrick Soukiassian, Universite de Paris-Sud "Selective Nanochemistry on Graphene and Silicon Carbide Surfaces & Interfaces: Nanotunnels and Possible Prebiotic Root of Life in the Universe"
WHERE: Physics    Seminar Room 107, 10 College Walk.

Seminar Flyer can be downloaded here. All welcome. Seats are limited, please RSVP your attendance here.

Abstract: The Moore’s law has powered the information-technology revolution since the 1960s. However, due to new needs and challenges, it is approaching its end. Thermal transport is becoming a major issue, requiring specific investigations, especially at low dimensional scales.    Graphene    &    silicon    carbide    (SiC)    are    advanced    semiconductors having figures of merit scaling well above those of well-established ones. SiC has a wide band-gap and is especially suitable for high-power, high-temperatures and high-frequencies devices/sensors and is biocompatible    and resistant    to    radiation&    damages,    with    the    same    thermal conductivity than copper.

Graphene, a 2D material made of a single atomic layer of C atoms in sp2 bonding configuration, has unsurpassed properties with a very large phase coherence lengths > 1 µm at 4 K, unprecedented high mobility at µ=250,000 cm2/V.s (1,360 cm2/V.s for Si). In addition, graphene has unsurpassed    ;spin    diffusion    lengths    exceeding    >    100    ?m    (few µm for Si), a thermal conductivity 10 times higher than Cu, and mechanically is the strongest material ever measured. Functionalization remains however challenging since interacting too strongly with a graphene layer may    alter its properties.    As    a    2D    single    atomic    layer material, graphene needs a substrate.

In this view, SiC is an excellent choice since “graphene” could be grown epitaxially on its surface. Understanding/mediating SiC-graphene surfaces & interfaces properties are of central importance toward functionalization. In addition, interacting with the SiC surface may offer an alternative    approach    to    successful    functionalization.    The    1st    case    of H/D-induced metallization of a semiconductor surface is shown for Si-rich 3C-SiC(001)-3x2 surface.

The 1st evidence of H/D-induced nanotunnel opening at semiconductor sub-surface for SiC is shown using advanced experimental techniques combining STM/STS, vibrational & 3rd generation Synchrotron Radiation-based photoelectron spectroscopies, and state-of-the-art calculations. Dangling bonds generated    inside    a    nanotunnel    offer    a    promising    template to capture atoms and molecules, opening nano-tailoring capabilities towards advanced electronics, chemistry, biotechnology, storage & sensors applications. Such a mechanism open routes toward selective functionalization of epitaxial graphene through    the    substrate.    Interestingly,    such    nanotunnels    have    also been recently predicted for C-terminated 3C-SiC(001)-c(2x2) surface.

Finally, another very amazing aspect is H atoms interaction with graphene on SiC dust grains, leading to polycyclic aromatic hydrocarbons (PAH) formation in the interstellar medium, a possible route toward prebiotic roots of life in the universe.

WHERE: Physics Seminar Room 107, 10 College Walk.

Seminar Flyer can be downloaded here. All welcome.

Abstract: Understanding the origin and properties of the different phases of materials and how to control them is at the heart of condensed matter physics and physics in general. One of the grand challenges of the field is to control spin-dependent properties without using magnetic    fields.    To    do    so,    one    must    resort to the relativistic nature of electrons, which arises directly from its particle-antiparticle description that gives its spin.

In the relatively slow world of solids this leads to the spin-orbit coupling (SOC) that connects the spin and charge of the electron. We have learned how to exploit the relativistic SOC to create new paradigms of spin control in complex materials and discover new unexpected connections between seemingly    disparate    ideas    as    topology,    materials    science,    high energy physics, ferromagnetism, thermoelectricity, and current-induced magnetization manipulation.

I will broadly describe joint theoretical and experimental efforts on how we now generate and manipulate spin-currents that are being used in devices relevant for future MRAM technology. I will also show in some detail how insights on the spin Hall effect have yielded novel ways to manipulate magnetization    using    relativistic    torques,    and    how    to extend these ideas to a new a phase of spintronics by exploiting anti-ferromagnetic materials in an active way.

Abstract: Atomically thin 2D Transition metal dichalcogenide (TMD) materials provide a wide range of basic building blocks with unique electrical, optical, and thermal properties which do not exist in their bulk counterparts. Our recent demonstration in vapor phase growth of TMD monolayer    MoS2 and WSe2 has stimulated the research in growth and applications. The growth of TMD layers is scalable and these layer materials can be transferred to desired substrates, making them suitable building blocks for constructing multilayer stacks for various applications. 2D monolayer    building    blocks    can    be    used    to form p-n junctions.

It is known that Moore’s law may not be valid in 7 nm technology nodes if we consider only Si or III-V semiconductors. 2D TMD materials are also promising materials for post-Si electronics, where their ultra-thin body structure may be able to serve for 5 nm and 3 nm technology nodes, meaning that  Moore’s    Law    could    be    further    extended    with these materials. We have demonstrated a 10 nm channel length of transistor based on MoS2 few layers using microelectronic compatible processes.

WHERE: Seminar Room 107, 10 College Walk.

Abstract: The Nobel Prize in Physics 2016 was awarded to David J. Thouless, F. Duncan M. Haldane and J. Michael Kosterlitz "for theoretical discoveries of topological phase transitions and topological phases of matter". In this colloquium I will try to explain the concept of a "topological    phase    of      matter"      and      the      impact      of      this idea on the study of electronic phases in solid-state systems.

Before the work of Thouless, Haldane and Kosterlitz, phase transitions were understood within Landau's framework of an order parameter arising from the breaking of a symmetry; for example the paramagnet to ferromagnet translation breaks rotational symmetry and establishes an order parameter (the magnetisation).    Thouless,      Haldane      and      Kosterlitz      (working      independently      or together in several different contexts) demonstrated that phase transitions may be accompanied by a change in the topology of a system, without a change in symmetry.

This framework allowed understanding of finite-temperature transitions in low-dimensional superfluids (the Kosterlitz-Thouless transition), spin chains (Haldane), the quantum Hall effect (Thouless), and the possibility of quantum Hall effects without magnetic fields (Haldane).

This last work was led ultimately to the discovery of a variety of topological phases of real solid-state materials which may form the basis of new types of electronic devices - which the FLEET Centre of Excellence is working to make a reality.

WHAT: MCATM Seminar: Topological Photonics with all-Dielectric Nanostructures & Metacrystals
WHERE: G30 New Horizons Centre.

Seminar Flyer can be downloaded here. Seats are limited so please RSVP your attendance. All welcome.

Abstract: We demonstrate experimentally the ability to control the subwavelength topologically protected optical edge modes by changing the polarization of the incident wave. In addition, we suggest theoretically and demonstrate experimentally that the photonic spin Hall effect can      be  enhanced  by  topologically      protected      edge      states.

Finally, we demonstrate that symmetry protected three-dimensional topological states can be engineered in an all-dielectric platform with the electromagnetic duality between electric and magnetic fields ensured by the structure design.

Abstract: Recently discovered atomically thin 2D materials have shown outstanding properties that differ from their bulk counterparts and are expected to lead to numerous applications in electronics, energy, chemistry, and mechanics. While much research efforts have been dedicated to          study          their          electronic          and        optical          properties,          their mechanical properties are under-explored. Using atomic force and friction force microscopy techniques, the mechanical and tribological properties of graphene, h-BN, and MoS2 were studied.

About the Speaker: A/Prof. Changgu Lee joined the department of Mechanical Engineering and SKKU Advanced Institute of Nanotechnology, Suwon, Korea in 2010 after his postdoctoral appointment at Columbia University, New York, USA working with Prof. James Hone. Lee completed his PhD at          Columbia          University          working          on          Power-MEMS          for small energy generation. His current research interest is surrounding the synthesis and nanomechanics of atomically thin materials such as graphene and transition metal dichalcogenides.

WHEN: 5 July 2016, 2:00 - 3:00PM
WHAT: MCATM Hosted Technical Seminar "Characterisation and Micro-Mapping of Thin Films and 2D Materials using Imaging Ellipsometry"
WHERE: Physics Seminar Room 107, 10 College Walk (Bld 27), Monash University          Clayton.          Enter          via          main          entrance          Physics Bld 19, 19 Rainforest Walk.

Traditional Ellipsometry is a well-known non-destructive optical method for determining film thickness and optical properties. The purpose of ellipsometry is to measure the change in polarization of light, reflected at an interface of interest, to obtain the optical thickness and the complex refractive          index          ;of          layers          that  much          thinner          than the wavelength of the observing light.

Imaging Ellipsometry combines the power of ellipsometry with optical microscopy. It achieves the highest lateral resolution in the field of ellipsometry and offers a very sensitive imaging technology for thin films. Typical samples are nanofilms like monolayers, SAMs and, tiny samples like 2D materials.          Image          shows          the          optical          differences          the thickness of graphene flakes.
