Abstract
Photostimulated exoelectron emission has been conjectured to be a consequence of a slip-step-induced resonant absorption of the incident UV light by the surface plasmons. This mechanism is examined in some detail by calculating the absorption ofp-polarized light by an oxidized metal with the slip steps represented by a sinusoidal interface between the metal and its oxide. Numerical results are discussed in terms of experimental results from aluminum and found to support the model. Further experiments are suggested.
