Abstract
Growth modes and properties of ultra-thin films of silver on a V(100) surface were studied by means of AES, XPS, UPS, TDS and LEED techniques. The experiments were carried out in a temperature range 50–1100 K. Above room temperature the films grow following the Stranski-Krastanov mode with two layers of silver serving as a substrate for clusters. The cluster formation rate strongly depends on adsorption (annealing) temperature. Below room temperature the films grow in an ordered way though not clearly layer by layer. At 50 K the growth is statistical. Silver and vanadium do not mix at their interface at any studied temperature. At small silver coverages (θ < 1 ML) desorption produces single peak spectra at 1000 K. Higher coverages show two peak spectra, the more dominant one being of zeroth order kinetics with onset at 950 K.
