Rd. Diehl et R. Mcgrath, STRUCTURAL STUDIES OF ALKALI-METAL ADSORPTION AND COADSORPTION ON METAL-SURFACES, Surface science reports, 23(2-5), 1996, pp. 43
The study of the adsorption and the coadsorption of alkali metals on s
ingle-crystal metal surfaces is a very active sub-field of surface sci
ence, partly because of the importance of technological applications (
promotion of catalytic reactions, enhanced oxidation, increases in ele
ctron emission rates), but also because of the fundamental interest in
how these ''simple'' adsorbates modify the surface. In the past few y
ears there has been a marked increase in the number of structural stud
ies of alkali adsorption and coadsorption systems, motivated in part b
y developments in theoretical models of adsorption. This article revie
ws recent studies of alkali adsorption and coadsorption using specific
ally structural techniques, with the intention of highlighting recent
developments, providing a useful reference base to the community, and
drawing attention to some unifying concepts.
