Abstract
The electronic structures of Pd and Pt epitaxial monolayers on Re and Ru (0001) surfaces are studied within a self-consistent semi-empirical scheme. To this purpose an s—d-electron tight-binding Hamiltonian is treated by the recursion method. The over-layer d bands are shifted to higher binding energies with respect to the corresponding elemental metal position. No charge transfer between atoms is supposed in our model. The experimental Pd core-level shifts are not far from the calculated chemical shifts although the agreement is not perfect.
