The reactions VN+1+H+→(VNH)+2 and (MgVN)0+H+→(MgVNH)+1 in GaN were investigated using density-functional theory. Estimates of the reaction rates indicate that (VNH)+2 and (MgVNH)+1 will form rapidly above 400°C, and modeling predicts that their populations will be substantial at elevated temperatures. These results indicate that compensation by VN is important in p-type GaN and that H suppression of VN formation is less effective than previously suggested.
