The authors have evaporated submonolayer to monolayer Sb films on the clean Au(110) surface and investigated the resultant Sb-induced reconstructions using low energy electron diffraction, x-ray photoelectron spectroscopy, Auger electron spectroscopy, and surface x-ray diffraction. They discovered a sequence of reconstructions, namely, c(2x2), (root 3 x root 3) R54.7 degrees, [GRAPHICS] and p (5x6), with increasing coverage of Sb. The well-known (2x1) reconstruction of the clean Au(110) surface changes to c(2x2) at an Sb coverage of theta approximate to 0.5 ML. At higher Sb coverages, there is a phase transition from c(2x2) to (root 3 x root 3) R54.7 degrees, with the (root 3 x root 3) R54.7 degrees pattern emerging at an Sb coverage of theta approximate to 0.7 ML. Upon further deposition, the superstructure spots of the (root 3 x root 3) R54.7 degrees reconstruction each split into two, resulting in the [GRAPHICS] pattern at a coverage of theta approximate to 0.8 ML. Finally, an Sb/Au(110)-p(5x6) reconstruction emerges at coverages in excess of 1 ML. They have also studied the temperature dependence of the c(2x2) surface phase. (c) 2008 American Vacuum Society.
