Abstract :
Layers of hexagonal GaN were grown on (111)B GaAs substrates by gas source molecular beam epitaxy (GSMBE) using hydrazine as a source of active nitrogen. Nitridation of an AlAs buffer layer was shown to produce a flat layer of AlN. GaN films grown on the AlN surface at growth temperatures above 700°C exhibited quasi two-dimensional growth. Photoluminescence spectra of such GaN layers show narrow band-edge emission and no “yellow” defect band
