Abstract
An electromagnetic radiation detector includes an inlet window intended to receive a stream of incident photons, as well as a photocathode in the form of a semiconductive layer. A conductive layer is deposited on the downstream face of the inlet window and a thin dielectric layer is disposed between the conductive layer and the semiconductive layer. The conductive layer is brought to a potential below that of the semiconductive layer so as to drive the photoelectrons out of the recombination zone and consequently improve the quantum yield of the photocathode.
