Abstract
To provide a light-emitting element where electrons are efficiently injected into a Ge light emission layer and light can be efficiently emitted, the light-emitting element has a barrier layerwhich is formed on an insulating film, worked in a size in which quantum confinement effect manifests and made of monocrystalline Si, a p-type diffused layer electrodeand an n-type diffused layer electroderespectively provided at both ends of the barrier layer, and a monocrystalline Ge light emission partprovided on the barrier layerbetween the electrodes. At least a part of current that flows between the electrodesflows in the barrier layerin a horizontal direction with respect to a substrate
