Abstract
Provided is a photocathode structure including: a photocathode including silicon (Si); an intermediate layer formed on the photocathode, and including a silicon oxide (SiOx); and a protective layer foiled on the intermediate layer, and including a metal oxide, wherein the intermediate layer is a tunneling barrier configured to transfer charges from the photocathode to the protective layer by an electric field applied from an outside.
