COMPOUND SEMICONDUCTOR LIGHT-EMITTING DEVICE |
摘要 |
This pn-junction compound semiconductor light-emitting device includes a crystal substrate; an n-type light- emitting layer formed of a hexagonal n-type Group III nitride semiconductor and provided on the crystal substrate; a p-type Group III nitride semiconductor layer formed of a hexagonal p-type Group III nitride semiconductor and provided on the n-type light-emitting layer; a p-type boron-phosphide-based semiconductor layer having a sphalerite crystal type and provided on the p-type Group III nitride semiconductor layer; and a thin-film layer composed of an undoped hexagonal Group III nitride semiconductor formed on the p-type Group III nitride semiconductor layer, wherein the p-type boron-phosphide-based semiconductor layer is joined to the thin-film layer composed of an undoped hexagonal Group III nitride semiconductor. ® KIPO & WIPO 2007
