摘要：

The effects of correlation on the surface potential of a dense electron gas are studied in the random phase approximation for an interacting system. The model considered is the same as that originally proposed by Juretschke and subsequently studied by Loucks and Cutler using the Bohm-Pines decoupling scheme. In the high density regime, we suggest as a reasonable approximation for the Slater average surface potential, the algebraic average of Juretschke's pure exchange potential and a Thomas-Fermi type screened exchange potential. The resulting theory yields substantial agreement with that of Loucks and Cutler as a function of effective screening parameter. © 1968.
