What is Electronic structure of the Au–Si(111) interface as a function of Au coverage about?

We have investigated the Au-Si(1 1 1) interface as a function of the Au coverage by the core-level photoemission spectroscopy. With increasing the Au coverage, the spectral features in the Si 2p core-level changed remarkably and some fine structures in both Si 2p and Au 4f spectra were observed. Based on the curve fitting analysis, the Si 2p and Au 4f spectra at more than 20 A ̊Au coverage were decomposed into three chemically different components, respectively. The assignments of their components were performed. In addition, we have compared these results for the Au-Si(1 1 1) interface with our previous study for the Au-Si(1 0 0) interface. It was found that the electronic structures for the Au-Si(1 1 1) interface is essentially identical to those of the Au-Si(1 0 0) interface except at the initial Au deposition.
