摘要

With 150KeV Mg~+ ion implantation, the optical and structural characteristics of GaN films were studied. Post-implant annealing up to 1000℃ was performed in N_2 ambient with a rapid thermalrnannealing (RTA) system, without an encapsulation layer. We observed a green band photoluminescence from Mg-implanted GaN. This green band photoluminescence should be associated with Mg induced defect-clustering in GaN. We also use the x-ray diffraction method to study the correlation between structure defects and implantation. We observed an extra shoulder peak at the small angle side of the GaN[0004] diffraction peak. The origin of this shoulder may be attributed to implanted magnesium induced GaN lattice strAlN.
