ADSORBED BARIUM FILMS ON TUNGSTEN AND MOLYBDENUM (011) FACE.

Work function and thermal stability of Ba–W(011) and Ba–Mo(011) systems as well as the structure of adsorbed barium films on the molybdenum (011) face are studied. From the structural analysis the data on absolute surface concentration of barium atoms are obtained. The work function, adsorption that, and some characteristics of barium surface diffusion are found to correlate with the structure of films. Phase transitions in the adsorbed films are observed.
