摘要：

An investigation was made of the properties of substrates with similar atomic structures - (011) faces of tungsten and molybdenum crystals - in the adsorption of strontium and lanthanum. The dependences of the work function and heat of adsorption on the concentration of adsorbed atoms on the surface were determined. The low-energy electron diffraction method was used to study the structure of submonolayer films. It was established that the properties of the Sr-W(011) and Sr-Mo(011) sytems differed relatively slightly, whereas the properties of the La-W(011) and La-Mo(011) systems differed quite strongly, which could be explained by the different proportions of the ionic and covalent components of the binding on adsorption of Sr and La. Differences were found between the structure of Sr films on monotypic faces of W and Mo crystals and these were attributed to the indirect interaction of adsorbed atoms via the substrate.
