Jellium surface
WebIt is well known that for high-density metals (r, < 3 a.u.) the jellium model fails in reproducing reasonable surface energies. In the case of finite clusters, the jellium model predicts too … http://archive.nstl.gov.cn/Archives/browse.do?action=viewDetail&articleID=a53f6c3f0be5fbc7&navig=9565bcbb40dbfbe9&navigator=category&flag=byWord&subjectCode=null&searchfrom=null

WebIn order to estimate the magnitude of the surface dipole potential and its variation with the charge density, we require a detailed model of the metal. Here we will explore the jellium model further, which was briefly mentioned in Chapter 3. Jellium is a good model for sp metals. This group of metals comprises, amongst others, the elements Hg, Cd, Zn, Tl, In, …
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.
