Abstract

A diode which emits white light when reverse-biassed consists of a semiconductor bearing a thick layer of semiconductor oxide (e.g. gallium arsenide oxide and/or alumina). On top of that is a metal (e.g. indium) contact pad. The light appears as a halo around the contact. A second contact on the oxide layer may be used in place of a direct connection to the semiconductor body.
