Study of Au Surfaces by Scanning Tunneling Microscopy.
01 January 1988
The reconstructions of Au surfaces have been studied by scanning tunneling microscopy. Topographs of Au(110)-(1x2) as a function of annealing temperature show changes in the long range order, in good agreement with diffraction measurements and theoretical studies. Some insight into the nucleation and growth of the (1x2) reconstruction was obtained by imaging the surface after deposition of Cs or O. A new structural model for Au(100)- (5x20) is proposed with a high resolution topograph. Adsorption of Si clusters on Au(100) will be described.
