BORON PHOSPHIDE SEMICONDUCTOR LIGHT-EMITTING DEVICE, METHOD FOR MANUFACTURING SAME, AND LIGHT-EMITTING DIODE |
摘要 |
A boron phosphide-based semiconductor light-emitting device, which device includes a light-emitting member having a hetero-junction structure in which an n-type lower cladding layer formed of an n-type compound semiconductor, an n-type light-emitting layer formed of an n-type Group III nitride semiconductor, and a p-type upper cladding layer provided on the light-emitting layer and formed of a p-type boron phosphide-based semiconductor are sequentially provided on a surface of a conductive or high-resistive single-crystal substrate and which device includes a p-type Ohmic electrode provided so as to achieve contact with the p-type upper cladding layer, characterized in that a amorphous layer formed of boron phosphide-based semiconductor is disposed between the p-type upper cladding layer and the n-type light-emitting layer. This boron phosphide-based semiconductor light-emitting device exhibits a low forward voltage or threshold value and has excellent reverse breakdown voltage characteristics. <IMAGE> |
