Abstract
In a semiconductor electron emission device for causing an avalanche breakdown by applying a reverse bias voltage to a Schottky barrier junction between a metallic material or metallic compound material and a p-type semiconductor, and externally emitting electrons from a solid-state surface, a p-type semiconductor region (first region) for causing the avalanche breakdown contacts a p-type semiconductor region (second region) for supplying carriers to the first region, and a semi-insulating region is formed around the first region.
