Wavefunctions and eigenvalues of image potential states

Methods for calculating wavefunctions and eigenvalues of image potential st ates are presented. We consider cases corresponding to metal-vacuum interfa ces, metal-dielectric medium interfaces and metal-dielectric medium-vacuum interfaces. We represent the metal as a perfect conductor or as a Fermi-Tho mas metal. We present the dependence of the wavefunctions and eigenvalues o f the image potential states on dielectric constants, electron affinity, wo rk function of the metal, and inverse Fermi screening parameter.
