Abstract
The adsorption of Tb, Dy and Er on a Mo(110) surface has been studied by means of AES, LEED, work function change measurements and quartz microbalance technique with the aim of understanding the evolution of the structure, structure-related properties and growth mode as a function of the adatom concentration, the adsorbate and the temperature. Although many similarities are found within investigated adsorbates some differences in details have been observed. The irreversible changes in work functions, submonolayer film structures and film growth modes, and a considerable decrease of the initial dipole moments of the adatoms observed at elevated substrate temperature, are probably determined by the change of the electronic states of the adsystems. The relation between the at present investigated initial dipole moments of RE atoms adsorbed on a Mo(110) surface and their electron structure is discussed.
