Research Interests
My research is focussed on the use of spectroscopic and microscopic methods in the analysis of semiconductors. The main materials of current interest to me are those based on the group III nitride quaternary system, AlxGayIn(1-x-y)N, and in particular nano-scale structures based on them. These have applications in many different areas, including solid-state lighting, data storage, communications and water purification. The techniques I use to study these materials include photoluminescence and electroluminescence spectroscopy, as well multiple modes of scanning electron microscopy (such as cathodoluminescence, electron beam-induced current and X-ray microanalysis). I am also interested in the application of multivariate statistical analysis techniques in the processing of the multidimensional data that these experimental methods yield.
Personal Statement
I am a Senior Research Fellow in the Department of Physics, where I have worked in the Semiconductor Spectroscopy and Devices research group since 2000. Prior to this, I studied at Imperial College London, Albert Ludwigs Universität Freiburg and Durham University. My PhD and post-doctoral work at Durham involved the use of scanning electron and optical beam techniques to study thin-film CdTe solar cells. I now apply similar techniques to characterise materials, nanostructures and devices made from group III nitride compounds.
