Abstract

A light-emitting thyristor includes a first semiconductor layer of a first conductivity type; a second semiconductor layer of a second conductivity type arranged adjacent to the first semiconductor layer; a third semiconductor layer of the first conductivity type arranged adjacent to the second semiconductor layer; and a fourth semiconductor layer of the second conductivity type arranged adjacent to the third semiconductor layer. The first semiconductor layer includes an active layer adjacent to the second semiconductor layer, the second semiconductor layer includes a first layer adjacent to the active layer and a second layer arranged between the first layer and the third semiconductor layer, and the first layer has a band gap wider than a band gap of the active layer and a band gap of the second layer.
