  • Abstract
    Secondary-electron-emission current measured from high-purity, single-crystal CVD diamond is found to increase when 3.1-eV photons are incident on the hydrogenated surface. Energy spectra indicate that the sub-gap illumination causes the band levels to shift in the bulk, thereby reducing the upwards band bending at the pinned surface.
