Available in PDF, EPUB and Kindle. Book excerpt: It was found that kinetics of decomposition of pure GaN powder without oxygen resulted in incongruent evaporation leading to the formation of the liquid gallium in the powder. A flow through configuration was also used because of its high collection efficiency of growth species. A mixture of Ga 2O3 and carbon powder as well as commercial GaN powder was used as precursors of gallium suboxide in this configuration. This configuration also demonstrated growth rates that are comparable to flow over configuration.
