Electron—Electron Interaction and Electron Correlation
2000The problem of electronic states in a solid is a many-body problem of a macroscopic number of particles since the electrons interact with each other through Coulomb repulsion. Since it is obviously impossible to solve such a formidable problem exactly, one has to resort to approximate methods.

On the electron-electron counterbalance hole
The Journal of Chemical Physics, 2008When a many-electron system has spatial inversion symmetry, the electron-electron counterbalance hole implies that two electrons with parallel spins cannot be at opposite positions with respect to the inversion center, and its presence was pointed out in the literature [T. Koga, J. Chem. Phys.

The potential a valence electron feels in a crystal is not a predetermined one. The electrons interact with each other by Coulomb forces and the one-electron theory is to be understood at most in the sense of a self-consistent approximation. Diagrammatic perturbation theory may lead to higher many-body corrections. In a semiconductor an electron in the

The Electron-Electron Interaction
1991In recent years, as device sizes have become smaller and carrier densities have become larger, the role of electron-electron scattering and screening have become very important in transport within semiconductor devices. The main difficulty in dealing with the electron-electron interaction lies in the nonlinear behavior of the interaction potential and ...

Electron screening and electron–electron scattering mechanisms
Journal of Electron Spectroscopy and Related Phenomena, 2013Abstract The roles of binary and multiple scattering are considered in the context of electron scattering and diffraction on the W(1 1 0) and W(1 1 0) + O(1 × 1) surfaces for energies from 10 to 40 eV. We define a binary scattering mechanism as the incident electron interacting with the field of a valence electron with conservation of the total ...

Electron-Electron and Positron-Electron Scattering Measurements
Physical Review, 1954A counter experiment is described which measures the absolute differential electron-electron scattering cross section in the energy interval 0.6 to 1.2 Mev and the absolute differential positron-electron scattering cross section in the energy interval 0.6 to 1.0 Mev.

According to our definition (cf. the introduction to Chapter 11) the electron-electron systems are specified by their initial states, in which there are either two negatons, two positons, or one negaton and one positon. The last case is of special interest, since it permits bound states; these states, however, are not stable.

Electron–electron interactions in the 2D electron system
Solid State Communications, 2007Abstract In this paper, we report studies of the electron–electron interaction effects in 2D electron systems. The interaction manifests in renormalization of the effective spin susceptibility, effective mass, g ∗ -factor, conductivity etc.

Electron sound in aluminum. Electron–electron scattering
Low Temperature Physics, 1998The relaxation parameters of charge carriers in aluminum are measured by investigating the attenuation of electron sound and acoustic wave transfer under Doppler-shifted cyclotron resonance. It is shown that the electron–electron relaxation rate at spherical parts of the hole sheet of the Fermi surface is close to the results of the theory (A.

The study of the electron-electron interaction in electron gun
Microelectronic Engineering, 1986Abstract The paper summarizes the up-to-date study of the electron -electron interaction of beam electrons in columns. The electron-electron interaction of beam electrons results in two effects to influence the electron optical properties of columns: the trejectroy displacement and the the energy spread which is called as Boersch effect.
