摘要： The invention relates to a semi-transparent photocathode (1) for a photon detector having an increased absorption rate for a preserved transport rate. According to the invention, the photocathode (1) includes a transmission diffraction grating (30) able to diffract said photons and provided in the support layer (10) on which the photoemissive layer (20) is deposited.

摘要： 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.
