Structures and Phase Transitions in Alkali Metal Overlayers on Transition Metal Surfaces

Abstract

Alkali metal adsorption has been studied for many years, primarily because of the great number of technological applications which arise from adding small amounts of alkali metal atoms to other materials. These include the promotion of catalytic reactions, increases in electron and ion emission rates of metals, and the enhancement of the oxidation of semiconductors. In recent years, alkali metal films have also been studied with a more fundamental view toward understanding the unusual interactions between adsorbed alkali metal atoms, the wide variety of surface structures which occur, and the phase transitions associated with them. Alkali metal adsorption has been the subject of several recent reviews1,2,3 and one book4 and the purpose of this chapter is not to provide a comprehensive review of this subject, but to discuss some alkali metal overlayer structures which display interesting behavior from the point of view of phase transitions.

    K. Müller, G. Besold, and K Heinz, in ref. 4. It should be noted that W(100) has a reconstructed surface below room temperature, and this naturally affects the Cs structures which occur. The adsorbed Cs also affects the reconstruction by suppressing the disordering temperature of the reconstructed superlattice.Google Scholar
