Web15 mag 1995 · Response functions employed are those for a jellium slab, so that electron emission mediated by bulk plasmons is described. Our results reproduce very well the experimental data reported by Rau, for the case of grazing incidence. In addition, we present calculations for the case of normal incidence. WebJellium, also known as the uniform electron gas (UEG) or homogeneous electron gas (HEG), is a quantum mechanical model of interacting electrons in a solid where the positive charges (i.e. atomic nuclei) are assumed to be uniformly distributed in space; the electron density is a uniform quantity as well in space. This model allows one to focus on the …

The Jellium model fitted the experimental data (Smith [89]) well than the Pseudojellium model (Lang and Kohn [90]. It is useful for calculating the electronic properties of alkali-metal slabs. Web24 lug 2006 · Wave-vector analysis γ xc (k), versus k ∕ 2 k F, of the RPA xc surface energy of a jellium slab of thickness a = 2.23 λ F and r s = 2.07. Solid and dashed lines represent exact RPA and LSDA RPA calculations, respectively. The LSDA calculation has been performed either from the actual RPA xc hole density of Eq. rancliffe arms nottingham

Metallic slabs: perturbative treatments based on jellium

WebConsider a system of N electrons in the external potential created by a jellium slab of uniform positive charge density. The slab extends from x = −L to x = 0 along the x-axis normal to the surfaces of area A, so we have N = A … http://people.physics.illinois.edu/Ceperley/papers/108.pdf Web31 lug 2008 · We present Hartree-Fock surface energies, work functions, and dipole barriers for a Jellium slab model at different electron densities and slab widths.
