| Abstract(in English) | Cubic GaN can be grown on (001) GaAs, but hexagonal phase is easily introduced in the grown layer. The cubic to hexagonal component ratio of the grown layer was investigated by XRD measurements using the ω scan. The optimum growth condition to obtain cubic-dominant GaN were found to be a thermal cleaning temperature of 600℃ and a V/III ratio of 300. With these growth conditions, a GaN layer whose cubic component was about 80% was grown on (001) GaAs. Furthermore, a strong emission at 377nm without any emission in visible region. |
