摘要

A new method for growing a GaN initial layer on a GaAs(0 0 1) substate is reported. The experiments show that the optimized growth conition for a smooth GaN initial laeyr is to grow a two monolayer thick layer at 600 deg C under As pressure. The pure cubic GaN films of 500 nm has been obtained on such an initial layer, the X-ray diffraction and photoluminescence show that the C-GaN film has a very high quality. There is no yellow or DA band emission of PL spectrum and the FWHM of the X-ray rocking curve is only 10 min.
