Abstract
The fully relativistic version of the screened Korringa-Kohn-Rostoker (SKKR) method is discussed and applied charge self-consistently to the (100), (110) and (111) surfaces of Au and Pt. In comparison to corresponding semi-relativistic calculations for Au it is found that spectral densities depend very crucially on the inclusion of relativistic effects. In terms of work functions, however, the difference between the semi-relativistic and the relativistic calculations is rather small.
