Abstract
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.
Claims9
A light-emitting element, comprising:
- 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 said light-emitting layer,
- whereby electron-electron hole pairs in said light-emitting layer are excited through the irradiation of electron beam from said irradiation source, to generate and emit a light.
A light-emitting element, comprising:
- 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 said light-emitting layer,
- wherein said island-shaped crystal portions are distributed in plural-stages in said base layer, to generate and emit a light of a given chromaticity over said light-emitting layer.
A light-emitting element, comprising:
- a light-emitting layer including a base layer made of a first nitride semiconductor, plural island-shaped crystal portions made of a second nitride semiconductor and at least one rare earth element, and
- an irradiation source of electron beam which is disposed so as to be opposite to said light-emitting layer.
