Abstract
Using an energetic model derived from the electronic structure, we stu dy the stability of the Various terminations of Pt1-cSnc (111) for 0<c <0.3, both in the disordered and in the ordered L1(2) structure. Moreo ver, using a kinetic Version of the model we reproduce the formation o f different surface alloys obtained experimentally by depositing Sn/Pt (lll). The relation between the equilibrium isotherm and the surface a lloys is then discussed via the local equilibrium concept.
