Statistical transfer rates associated with higher-symmetry potential-energy wells in solids: Application to photoinduced desorption and electrification

A current series of papers on barrier-controlled and trapping processes in solids and/or at solid surfaces have laid down the emphasis onto describing the statistical event by means of the barrier currents method due to Bardeen and Christov. The present study centered on photodesorption and photoelectrification is the fourth of an arXiv series which also included rapid statistical approaches to nucleation, diffusion and drift currents in state of the art materials. We presently extend our arguments to spherical square and oscillatory wells to deal with the photoprocesses.
