Abstract

Exemplary metamaterial photocathodes enable detection of light from visible through long wave infrared wavelengths. Metamaterial stacks, comprising gold, silicon, and cesium-oxide, coupled to a semiconductor allow hot electrons to efficiently enter a vacuum. The hot electrons are multiplied in a multichannel plate and directly through another vacuum towards a phosphorus screen.
