Au induced reconstructions on Si(111)
Au adsorption induces a vast variety of different reconstructions on Si(1 1 1). In a combined scanning tunneling microscopy and spot-profile analysis-low energy electron diffraction study we have observed for the first time an Au induced (2×2)-Au and View the MathML source-Au surface reconstruction. The atomic structure of the metastable View the MathML source-Au reconstruction is described as View the MathML source-Au structure with an ordered arrangement of super-heavy domain walls.
