Abstract:

This years work was concerned with the electronic structure of ZnO and related alloys. The nature of the valence band fine structure was studied and progress made in identifying the problems underlying its identification by experimental optical studies. Valence band effective mass parameters were determined. The electronic structure of MgxZn1-xO alloys were studied, their bandgap bowing determined and their band offsets to ZnO and other related materials were investigated. The stability of MgO in the wurtzite structure relative to the rocksalt structure was investigated. A continuous transformation from rocksalt to wurtzite was discovered and applied both to MgO and to GaN.
