摘要
This work constitutes an analysis of the thermodynamic properties in the ordered metallic surface alloy system Au(111)-(root 3 x root 3)R30 degrees-Pd. The equilibrium structural characteristics as well as the thermodynamic functions are examined by the matching method, associated with real space Green's function formalism, evaluated in the harmonic approximation. Our numerical results, for this metallic system of surface alloy, show in particular a significant dependence between the thermodynamic properties and the coordination number and the values of the force constants.
