中文摘要	the gan-rich side of ganp ternary alloys has been successfully synthesized by light-radiation heating and low-pressure metal-organic chemical vapor deposition. x-ray diffraction (xrd) rocking curves show that the ( 0002) peak of ganp shifts to a smaller angle with increasing p content. from the ganp photoluminescence (pl) spectra, the red shifts from the band-edge emission of gan are determined to be 73, 78 and 100 mev, respectively, in the ganp alloys with the p contents of 1.5%, 5.5% and 7.5%. no pl peak or xrd peak related to gap is observed, indicating that phase separation induced by the short-range distribution of gap-rich regions in the ganp layer has been effectively suppressed. the phase-separation suppression in the ganp layer is associated with the high growth rate and the quick cooling rate under the given growth conditions, which can efficiently restrain the accumulation of p atoms in the ganp layer.
