Abstract

Surface-sensitive x-ray scattering techniques with atomic scale resolution are employed to investigate trie microscopic structure of the surface of three classes of liquid binary alloys: (il Surface segregation in partly miscible binary alloys as predicted by the Gibbs adsorption rule is investigated for Ga-In. The first layer consists of a supercooled In monoiayer and the bulk composition is reached after about two atomic diameters, (ii) The Ga-Bi system displays a .wetting transition at a characteristic temperature T_w≈220°C. The transition from a Bi monoiayer on Ga below T_w to a thick Bi-rich wetting film above T_w is studied, (iii) The effect of attractive interactions between the two components of a binary alloy on the surface structure is investigatec for two Hg-Au alloys.
