Electron–electron and electron–positron bremsstrahlung

Radiation Physics and Chemistry, 2006
Abstract The bremsstrahlung emitted in electron–electron (e–e) and electron–positron (e - –e + ) collisions is investigated. After a short description of the kinematics, cross sections exact to lowest-order perturbation theory are presented and compared with available approximations, and experiments on the two processes are ...

Electronic detectors for electron microscopy

Quarterly Reviews of Biophysics, 2011
AbstractElectron microscopy (EM) is an important tool for high-resolution structure determination in applications ranging from condensed matter to biology. Electronic detectors are now used in most applications in EM as they offer convenience and immediate feedback that is not possible with film or image plates.

Electron—Electron Interaction and Electron Correlation

2000
The 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.

Electronic detectors for electron microscopy

Current Opinion in Structural Biology, 2007
Due to the increasing popularity of electron cryo-microscopy (cryoEM) in the structural analysis of large biological molecules and macro-molecular complexes and the need for simple, rapid and efficient readout, there is a persuasive need for improved detectors.

On the electron-electron counterbalance hole

The Journal of Chemical Physics, 2008
When 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.

Electron screening and electron–electron scattering mechanisms

Journal of Electron Spectroscopy and Related Phenomena, 2013
Abstract 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 Interaction

2018
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

1991
In 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–electron interactions in the 2D electron system

Solid State Communications, 2007
Abstract 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.

The Electron-Electron System

1976
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.
