Light emission from semiconductor integrated circuits

Abstract

Structures and methods to inject electrons into an insulator from a semiconductor layer that are then collected in a thin layer of a direct semiconductor material which in turn emits light by bandgap recombination.

1 . A multilayer light emitting device, comprising: 
 an electron emitting layer;    an insulating layer over the electron emitting layer; and    a light emitting layer over the insulating layer;    wherein electrons emitted from the electron emitting layer pass through the insulating layer and into the light emitting layer and are converted into bandgap radiation by the light emitting layer.
