The KOH etching effects of a GaN buffer in the MOVPE growth of InN on sapphire have been studied. With increasing etching time, the number of GaN grains is decreased and, as a result of that, the grain size of InN is markedly increased. The grain size of InN grown on the 10 min-etched GaN buffer is larger than that of a film grown without GaN buffer. When the GaN etching time is less than 5 min, one InN grain is grown on about ten GaN grains on average. For the etching time of 8-10 min, one GaN grain acts as a nucleation center for one InN grain and no InN nucleation occurs in the areas without GaN grains on the sapphire substrate. The diffusion length of InN species on the sapphire substrate is estimated to be about 1 μm or more. In spite of the enhanced grain growth of InN films grown on the etched buffers, their electrical properties are almost same as those grown without etching. |
