LUMINESZENTES HALBLEITERELEMENT.

摘要

A semiconductor optical device in which a hetero-structure is constructed by sandwiching a semiconductor layer including a thin film made of a semiconductor or insulator between semiconductors having a larger band gap than that of the thin film so that the electron-hole pairs generated through the thin film may recombine by the tunnel effect to emit an optical beam. The optical device is equipped with electrodes for controlling the probability of said recombination.
