Abstract
Growth of high-quality and/or "purely cubic" GaN layers on (001) GaAs has been investigated by an rf-radical source MBE paying particular attention to the effect of surface cleaning and smoothing on the structural properties of the GaN epilayers. Device-quality c-GaN layers can be grown on the (001) GaAs treated by atomic hydrogen at high temperatures; the FWHM of X-ray rocking curve for the c-GaN (002) plane is as small as 80-90 arcsec and also the inclusion of the hexagonal phase GaN in the epilayer can be less than 4×10-3.
