This work describes the effect of nucleation time on GaN layer; which was grown separately on three different shape of patterned sapphire substrate (PSS); cone PSS and dome PSS. Prior to the GaN layer growth, a low temperature of GaN nucleation layer was initially grown at 40, 80 and 160 second. Th...
