Abstract : The objective of this study has been to conduct an analytical investigation of the interaction of light with electrons in the interior of a metal and near its surface. The surface and volume photoelectric effects, or photons with less energy than the metal work function, are computed using a second order perturbation theory. It is found that electrons excited in the interior of the metal by a photon-electron-phonon interaction can escape from the metal giving rise to a volume photoelectric effect below the normal interband volume photoelectric threhshold. This effect, however, is much smaller than the surface photoelectric effect. This study is part of a program undertaken to examine the capabilities of lasers to free electrons from metals into vacuum for electronic application. (Author)
