摘要：

The surface shifts of the Cd 4d and S 2p core levels of the wurtzite CdS(101̄0) surface have been measured. The shifts for the Cd4d and S2p levels were 0.39 and -0.43 eV, respectively. The experimental surface shifts are compared to calculated initial state surface shifts from a simple model due to Mönch. It is found that the reduced Madelung potential at the surface alone can explain the experimental observations. A comparison to recently measured surface shifts of cubic CdTe(110) is performed within the same model and the structural aspects of the different surfaces are found to be fully reflected in the magnitudes of the shifts. © 1990.
