Paper Abstract

Light can emit from light emitting transistor of III-V materials. The pn-n+ structure of light emitting transistor, which has an additional n-n+ heterojunction between the base and electron emitter, is suggested. The base voltage can control the light output effectively. The functional principle of light emitting transistor is illuminated. A model about the abrupt isotype heterojunction in the base has been utilized to describe thermionic electron transport, current density and potential barrier in such a device. The model is used to explain the underlying mechanisms of the present devices.
