For more details, see our new group website: Functional Nitrides Group

I'm a Royal Society University Research Fellow and I lead the Functional Nitrides group in the Department of Materials at Imperial which currently includes 4 PDRAs, 12 PhDs and 2 MEng students. Our work centres primarily on (i) developing broad, mutually compatible, new 'palettes' of materials from which future electronic devices can be created, and (ii) the control of material properties using artificial structuring on the nanoscale. Current research focuses on developing new III-nitride-based multifunctional materials for use in a broad range of applications, ranging from UV light emitters for water treatment in the developing world, through energy harvesters for clean energy generation, to exotic new devices enabled exclusively by the properties of the device material 'building blocks' that we create. A recent major award from the EPSRC brings the group's total funding to over £4 million and now allows us to extend this work into functional oxynitrides and carbonitrides and into elements spanning the majority of the Periodic Table.

The group combines both theory and experiment to help guide device material development. Experimentally, we focus on epitaxial thin film deposition by molecular beam epitaxy and electron beam epitaxy and on material characterisation using advanced electron microscopy techniques, synchrotron-based X-ray techniques, SIMS and our new in-situ UHV characterisation suite for air-sensitive materials. The group also collaborates extensively with the University of Cambridge, where I remain an academic visitor.

Prior to joining Imperial as a Lecturer in 2011, I spent 5 years developing III-nitride semiconductors as an independent Oppenheimer Research Fellow and Jesus College Research Fellow at the Departments of Materials Science and Physics at the University of Cambridge. This followed my PhD at Cambridge in the same research area. My work on III-nitride semiconductors continues presently, in parallel with the growing area of functional nitride material development.
