ABSTRACT:
A photocathode device is disclosed including an active layer, a composition ramp layer and an emission layer including an emission surface. The active layer, ramp layer and emission layer each have both a predetermined material composition and a predetermined doping level for maintaining the conduction band of the device flat until the emission surface which functions to increase the photoresponse of the device.
