ABSTRACT:
A semiconductor cold emission device comprising at least two different semiconductors and a junction with a first region having n-type conductivity and a second region which is a p-type conductivity and an indirect transition type material whose effective forbidden bandwidth is smaller than that of the first region and means for applying voltage to the junction to cause electrons injected from the first region to the second region to be emitted from the surface of the second region to the exterior.
