Abstract

An FED (10) utilizes a semiconductor junction to control the current flow (32) through an emission tip of the FED (10). The semiconductor junction is created between a conductive layer (12) and a doped semiconductor layer (14). The conductive layer (12) can be a metal or another doped semiconductor layer in order to form the semiconductor junction.
