SUMMARY The reconstructions of Au surfaces have been studied by scanning tunnelling microscopy. Topographs of Au(110)‐(1×2) 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 (1×2) reconstruction was obtained by imaging the surface after deposition of Cs or O. A new structural model for Au(100)‐(5×20) is proposed with a high resolution topograph. Adsorption of Si clusters on Au(100) will be described.
