چکیده انگلیسی
The atomic structure and charge distribution of Ag adsorbed Ge(0Â 0Â 1) surfaces have been investigated by means of Ge 3d core- and Ag 4d core-levels photoelectron spectroscopy. A mono-atomic layer of Ag was deposited on the clean Ge(0Â 0Â 1) c(4Ã2) surface at 80Â K. The Ge 3d spectrum measured at 80Â K was deconvoluted into two surface components, which is consistent with the previously proposed Ag ad-dimer model. After annealing the surface at room temperature, the rearrangement of the charge distribution was revealed to include electron transfer from Ge to Ag in conjunction with the surface restructuring process by the annealing.
