Abstract

The near band gap photoelectric emission and field emission properties of diamond are investigated. Our results find three characteristic photoelectric yield spectra which have been observed from both polycrystalline CVD diamond films and single crystal diamond. The categories correspond to differences in bulk doping/surface preparation and illustrate the importance of band bending at the surface. Field emission experiments also find that the same three categories have distinct field emission properties. Our field emission observations are discussed in terms of electron transport properties from the bulk to the surface.
