Abstract
Changes in the work function and adsorption energy of ultrathin layers of Dy, Nd and Li deposited on preoxidized Mo(112) and W(111) faces ha ve been investigated using the method of CPD and adsorption isobars. I t has been found that the preadsorbed oxygen brings about a lowering o f the work function minim um for the co-adsorption system and increasi ng of the area occupied by the metallic adsorbate, that is relevant to the work function minimum. Discussed are the results obtained for dif ferent values of initial oxygen coverage. (C) 1998 Elsevier Science Lt d. All rights reserved.
