The underpotential deposition (UPD) of Ag has been discussed on Au(111) in sulfuric acid solutions. The structure of the first adlayer of Ag is ( square root 3* square root 3)R30 degrees in a 'pure solution'. The atomic image of the hydrogen-terminated Si(111) surface has also been reported. The ideal Si(111):H-1*1 surface persists in solution for several hours.
