The structure of the liquid-vapor interface of a gallium-tin binary alloy

摘要

We report the results of self-consistent quantum Monte Carlo simulations of the structure of the liquid-vapor interface of the alloy Sn_(0.09)Ga_(0.81). Our calculations are in very good agreement with the experimental results reported by Lei, Huang and Rice [J. Chem. Phys. 107, 4051 (1997)]. In particular, our calculations confirm the experimentally inferred existence of a partial second layer of Sn below the complete outermost layer of Sn in the structured liquid-vapor interface of this alloy.
