Abstract

The structure and growth mode of ultra-thin Fe films on a Rh(100) single crystal surface were investigated by angle-resolved Auger electron spectroscopy (ARAES) and lowenergy electron diffraction(LEED) in an ultra high vacuum system. Fe films were prepared by evaporation on an Rh substrate kept at room temperature from an Fe plate heated by a tungsten filament. The angular distributions of the Rh and Fe Auger electrons were measured along the two azimuth, [010] and [110] of the (100) surface. The results show that Fe films grow via a layer-by-layer growth mode and have an fcc structure on the Rh surface.
