摘要：
The structure of the (square-root 3 X square-root 3)R30-degrees-Au/Si(111) surface is investigated using first principles total energy calculations. Most models proposed by experiments have been tested. The lowest energy model is a conjugate honeycomb-chained-trimer (CHCT-1) configuration which consists of a top layer of trimers formed by Au atoms lying above a "missing top layer" Si(111) substrate with a honeycomb-chained-trimer structure for its first layer. The electronic charge densities from bands around the Fermi level give a good description of the images observed in STM experiments.
