Observation of the Surface State Resonance Effect by the Convergent Beam RHEED Technique

Abstract

The angular dependence of the specular spot intensity reflected from a ZnS (110) surface has been analyzed by using Bethe's: dynamical theory. Many-beam calculations have been carried out with simple surface potential models. The calculations showed that the angular dependence of the intensity changed very sensitively with the surface potential shape at the surface state resonance positions. One of the models was in very good qualitative agreement with the present experimental result.
