Microscopic structure of the wetting film at the surface of liquid Ga-Bi alloys

X-ray reflectivity measurements of the binary liquid Ga-Bi alloy reveal a dramatically different surface structure above and below the monotectic temperature T(mono) = 222 degrees C. A Gibbs-adsorbed Bi monolayer resides at the surface in both regimes. However, a 30 A thick, Bi-rich wetting film intrudes between the Bi monolayer and the Ga-rich bulk for T>T(mono). The wetting film's internal st...

Ab initio molecular-dynamics simulation of liquid Ga-Ge alloys

We report the results of ab initio molecular-dynamics simulations of liquid Ga-Ge alloys at four different concentrations. The physical quantities studied include the partial structure factors, bond-angle distributions, self-diffusion coefficients, electronic density of states, and the electrical conductivity. The introduction of Ga causes a distinct reduction of the shoulder in the structure f...

Liquid phase-enabled reaction of Al-Ga and Al-Ga-In-Sn alloys with water

The water-reactivity of AleGa and AleGaeIneSn alloys is investigated as a means to utilize the chemical potential energy of Al to split water for the production of H2. Al in bulk quantities of these alloys participates in a heterogeneous reaction with water to produce H2 and a-Al(OH)3 (bayerite). Low melting point phases in these alloys are believed to enable the observed reaction upon liquefac...
