Scanning-tunneling-microscopy studies of the oxidation of Ge(111)-c(2x8)

Scanning tunneling microscopy was employed for an investigation of the oxidation process of the Ge(111)-{ital c}(2{times}8) surface at room temperature. Images of the same area of the surface were obtained for various exposures of oxygen. The results show that the oxidation proceeds by nucleation fo...

Description
Summary:Scanning tunneling microscopy was employed for an investigation of the oxidation process of the Ge(111)-{ital c}(2{times}8) surface at room temperature. Images of the same area of the surface were obtained for various exposures of oxygen. The results show that the oxidation proceeds by nucleation followed by expansion of the oxidized area.
