Abstract

Photostimulated field emission (PSE) should prove to be an extremely useful probe of electronic states. We report on a generalization and extension of a previous theory to the case of a simple triangular barrier model of the surface potential. Results for both dj dε{lunate}, the differential current per unit energy, and j F2 are presented, where F is the applied electric field. These differ from the approximate results of Bagchi which are not valid at high field. The dependence of J on the transmission coefficient is shown to arise in a natural way.
