Abstract

Abstract The double systems BaORe (0001) and OBaRe (0001) have been investigated by LEED and contact potential difference techniques. It is shown that the diffraction patterns in both cases were identical to those obtained for BaO films on the (0001) Re face described in the preceding paper. The analysis of the changes of the work function during the deposition of barium on an oxygen covered substrate suggests the existence of two phase adsorption of oxygen on that crystal face. The results obtained are compared with data for double LiOW (110) and NaOW (112) systems.
