TRANSMISSION PHOTOCATHODE

摘要

This transmission photocathode (2) has the following: a light-transmitting substrate (4) that has an outside surface (4a) upon which light is incident and an inside surface (4b) from which the light incident upon the outside surface (4a) exits; a photoelectric conversion layer (5) that is provided on the inside-surface (4b) side of the light-transmitting substrate (4) and converts the light exiting said inside surface (4b) into photoelectrons; and a light-transmitting electrically conductive layer (6) that is provided between the light-transmitting substrate (4) and the photoelectric conversion layer (5) and comprises graphene.
