Surface effects of ordering in binary alloys

This article reviews the most important achievements in the studies of the compositional (chemical) and magnetic ordering effects in the surface region of single-crystal binary alloys with different bulk structures. These alloys include the non-magnetic and magnetic concentrated substitutional binary systems which have a tendency to ordering (Au–Cu, Cu–Pt, Fe–Pt, Co–Fe, Fe–Ni, Al–Fe, Al–Ni, Pt–...

Molecular-dynamics study of surface segregation in liquid semiconductor alloys

We report the results of a molecular-dynamics study of the surface tension and surface profile of liquid Si and Ge (l -Si and l -Ge! and their alloys using empirical Stillinger-Weber potentials. The calculations are carried out at two temperatures slightly above the melting temperatures of Si and Ge and the alloys Si 0.8Ge 0.2 and Si 0.2Ge 0.8 . They show clear evidence of surface segregation b...
