Abstract
A method of producing electrons via photoemission comprising providing diamond doped p-type with boron, treating a surface of the diamond by exposing it to atomic hydrogen inside an ultrahigh vacuum chamber, illuminating the surface with photons, and extracting the photoemitted electrons. A chemically stable visible light photoemission electron source comprising a diamond film having a surface terminated with hydrogen and a light source.
