Research interests
My research interests lie in the development and evolution of process-induced defects in semiconductors, originally ion implantation damage in silicon and silicon-germanium, and more recently in wide band gap materials such as semiconducting diamond and GaN. Such studies are in support of electronic device development. I use a variety of electrical characterisation techniques, such as current-voltage and capacitance-voltage measurements as well as deep level transient spectroscopy in this work.
I have a keen interest in multidisciplinary work, and am leading a project to develop an "intelligent" pressure cuff for the lower leg. I also am heavily involved in 'What's in my stuff', an interdisciplinary research project which brings together science and art with the aim of raising awareness about the materials contained within some of the objects we own.
PhD students working with me currently are: Ali ElHaji (GaN) and Osama El-Sherif (diamond and GaN).
