Development of methodology to determine oxygen and hydrogen content in GaN and its application to problems of doping and compensation.

Project Member(s): Phillips, M.

Funding or Partner Organisation: Australian Research Council (ARC Large Grant)

Start year: 2001

Summary: The project aims to provide an innovative procedure for accurate optical and electron probe analysis of oxygen and hydrogen in gallium nitride, where effects of nonuniformities are significant and cause serious problems for device fabrication. Systematic high resolution X-ray spectroscopy studies combined with scanning cathodoluminescence, Raman and adsorption spectroscopies will be used to resolve a wide range of technologically important problems relevant to efficiency of doping, compensation and contact processing technologies in GaN.
