Sažetak
The growth and structure of ultrathin silver films (1-5 ML) deposited on a reconstructed V(100)-(5x1) surface are studied by use of STM, AES, and RPES. To model the structure of the system we have also performed first principles calculations. It has been established that due to the annealing of deposited silver uniform films are formed and that the vanadium reconstruction is completely removed. As found from STM measurements and supported by ab initio calculations in the in-plane direction silver follows the structure of the V(100)-(1x1) lattice and is tetragonally distorted in the direction perpendicular to the surface. The ab initio results predicted the adsorption energies of individual silver layers and the work function of Ag/V(100) in accordance with experiments.
