Abstract

The structure of surface barrier resonances in LEED is shown to be strongly dependent upon the shape and position of the potential energy barrier at the crystal surface. This suggests that systematic high-resolution measurements of LEED intensities in the energy range of surface barrier resonances may be a useful tool for studies of surface barrier structure. Such measurements should be performed at several angles of incidence and at a variety of azimuths with primary beams of very low energy (<30 eV).

Computations are presented for a model crystal surface of Cu(001) to illustrate these conclusions. The results are in agreement with McRae's model for the surface barrier resonance in LEED.
