Abstract:
1. A light-emitting diode comprising: a first conductive type silicon single crystal substrate; a light-emitting section including a first pn junction structure composed of a III-group nitride semiconductor on the silicon single crystal substrate; a first polarity ohmic electrode for a first conductive type semiconductor provided on the light-emitting section; and a second polarity ohmic electrode for a second conductive type semiconductor on the same side as the light-emitting section with respect to the silicon single crystal substrate, wherein the second conductive type semiconductor layer comprises a boron phosphide (BP) base semiconductor and is directly joined to the silicon single crystal substrate, and the first conductive type silicon single crystal substrate and the second conductive type semiconductor layer form a second pn junction structure in a region which extends from the silicon single crystal substrate to the light-emitting section.
