Abstract
In this work we employ the state-of-the-art pseudopotential method, within a generalized gradient approximation to the density functional theory, combined with a recently developed method for the calculation of HREELS spectra to study a series of different proposed models for carbon incorporation on the silicon (0Â 0Â 1) surface. A fully discussion on the geometry, energetics and specially the comparison between experimental and theoretical STM images and electron energy loss spectra indicate that the Si(1Â 0Â 0)-c(4Â ÃÂ 4) is probably induced by Si-C surface dimers, in agreement with recent experimental findings.
