摘要：

An embedded atom model recently developed to simulate the glass transition in metal-Si alloys is applied to study the surface structure, thermodynamics and dynamics of a prototypical amorphous metal alloy, i.e., Pd80Si20. Our computation shows that a sizable surface mobility is still present 100 K below the bulk glass temperature T-g, thus enhancing relaxation and ordering at the surface with respect to the amorphous bulk.
