My research is broad and covers three main areas: gallium nitride materials and devices; advanced electron microscopy; and high-temperature aerospace materials.
Gallium-nitride materials and devices
Gallium nitride (GaN) is probably the most important semiconductor material since silicon. It emits brilliant light as well as being a key material for next-generation transistors.
Advanced electron microscopy and analysis
We are developing and applying a range of advanced electron microscopy techniques. For example, we have pioneered energy-filtered secondary-electron imaging in scanning electron microscopy for the mapping of dopants in silicon and other semiconductor devices.
High-temperature aerospace materials
We are designing and developing higher-temperature advanced alloys that will improve the efficiency of gas-turbine engines, resulting in reduced fuel consumption and reduced emissions.
