Abstract

Kyma Technologies will team with North Carolina State University to develop growth techniques using the hydride vapor phase epitaxy technique to fabricate large area non-polar GaN substrates. Using high quality non-polar seed crystals developed during the Phase I effort, the HVPE growth process will be optimized to increase the GaN crystal size and result in large area substrates. Kyma will perform the crystal growth and materials characterization; North Carolina State University will perform MOCVD growth and materials characterization, in addition to developing a growth model relating Kyma's physical-chemical growth parameters to atomic growth phenomena.
