Homoepitaxial growth of Au on Bi-covered Au(111) was studied at room temperature using reflection high-energy electron diffraction (RHEED) and Auger electron spectroscopy (AES). From observations of RHEED it is found that the Au(111) (23×1) reconstruction structure changes to a (1×1) by about 0.16–0.5ML deposition of Bi and to a (2√3×2√3)R30° by about 1.0ML deposition of Bi, respectively. The surface...
We have investigated the effect of Ag on the homoepitaxial growth of Fe(100) by means of reflection high-energy electron diffraction (RHEED). It was clearly found that Ag enhances layer-by-layer growth of Fe on Fe(100)-c(2x2)O reconstruction surface. The result of the dependence of the growth behavior as a function of Ag layer thickness suggests that there exists the most suitable amount of Ag surfactant...
