摘要: In a semiconductor light-emitting element, an underlayer is made of AlN layer, and a first cladding layer is made of an n-AlGaN layer. A light-emitting layer is composed of a base layer made of i-GaN and plural island-shaped single crystal portions made of i-AlGaInN isolated in the base layer. Then, at least one rare earth metal element is incorporated into the base layer and/or the island-shaped single crystal portions.

摘要: In a semiconductor light-emitting element, an underlayer is made of a high crystallinity Al-including semiconducting nitride material of which the FWHM is 90 seconds or below in full width at half maximum of an X-ray rocking curve. A light-emitting layer is made of a semiconducting nitride material including it least one element selected from the group consisting of Al, Ga and In and containing at least one element selected from rare earth metal elements. The light-emitting layer can be omitted if at least one element selected from rare earth metal elements is incorporated in the underlayer.

摘要: A light-emitting element includes a light-emitting layer including a base layer made of a first nitride semiconductor and plural island-shaped crystal portions made of a second nitride semiconductor, and an irradiation source of electron beam which is disposed so as to be opposite to the light-emitting layer. Then, electron-electron hole pairs in the light-emitting layer are excited through the irradiation of electron beam from the irradiation source, to generate and emit a light.
