My research interests centre around developing techniques for atomic resolution imaging of materials in transmission electron microscopy and scanning transmission electron microscopy. This requires a detailed analysis of the elastic and inelastic scattering behaviour of fast electrons moving through material specimens. Using theoretical modelling and numerical simulation, I work closely with experimental collaborators to tease out the maximum of scientific information from experimental microscopy images.
Topics of current, particular interest include:
- Establishing an "absolute scale" such that the comparison of experimentally recorded and theoretically calculated intensities can be used to count the number of atoms in a column of atoms.
- Developing the recent technique of annular bright field imaging for the direct imaging of light elements using scanning transmission electron microscopy.
- Using a combination of simultaneously acquired images for novel imaging possibilities.
- Adapting simulations to non-periodic specimens: grain boundaries, few atom impurities, defects.
Research projects available
A list of proposed Honours level projects for 2012 can be found in the School of Physics Guidelines and proposed research projects available here. This list is not exclusive; projects are flexible and may evolve. Please feel free to come and talk with me at any time if you are considering physics honours and are interested by any of these topics.
PhD level projects are also possible. Please contact me at any time to discuss the possibilities.
