Jellium surface

Web1 ago 1981 · Electronic density profiles and surface energies are calculated for metal surfaces over a wide range of densities in the jellium approximation. The theory makes use of correlated wave functions, which consist of determinants of model single particle orbitals (taken to be solutions for a variational surface potential) modified by a pair correlation … Web出现检索词的位置. 文章任何位置. 位于文章标题

WebOne of the earliest treatments of a metal surface was based upon a jellium model (Bardeen, 19.36). If the electron gas terminated abruptly at the surface of the jellium there would be no net potential to contain the electrons in the metal. Therefore the electron gas extends beyond the metal, giving a dipole layer, as illustrated in Fig. 17-5. WebSolvated Jellium Method ...

Position of the image plane in the jellium model. The surface potential of an electron in the jellium model is calculated using the local-density approximation. By fitting the numerically calculated surface potential with the classical image potential, Eq. (4.7), the position of the image plane is obtained as a function of r, and z.
