Electron-electron interaction in projectile electron loss
Physical Review A, 1991In ion-atom collisions where the projectile is ionized, target electrons act not only coherently by screening the target nucleus but they may also act incoherently by directly ejecting a projectile electron. This electron-electron interaction should be relatively most important for targets that have a low nuclear charge, since the cross section for a ...

Electron heating in GaAs due to electron-electron interactions
Physical Review B, 1994The interactions of hot electrons in semiconductor layers are usually studied assuming the scattering mechanisms affect only the injected hot electron distribution, leaving the cold electrons and the lattice in thermal equilibrium. However, if the energy transfer from hot to cold electrons is sufficiently large the cold electron distribution can be ...

Electron-electron scattering in hot electrons
Semiconductor Science and Technology, 1992The influence of electron-electron scattering on the parameters of a hot electron system in a semiconductor has been analysed. The strongest influence has been observed in the slightly heated electron system (in the case of so-called 'warm electrons') at the lattice temperature T approximately=To/5(To being the characteristic temperature of the optical

Electron-Electron Interaction in Warm Electrons
Journal of the Physical Society of Japan, 1962Effects of the electron-electron interaction on the distribution function of warm electrons in semiconductors are investigated by the Born approximation with a screened Coulomb potential. The theory shows that the effect of the e - e interaction is remarkable, unless the density of the electrons is quite small.

Electronic detectors for electron microscopy
Quarterly Reviews of Biophysics, 2011AbstractElectron 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.

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.

Electronic detectors for electron microscopy
Current Opinion in Structural Biology, 2007Due 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.

Electronic markets and electronic hierarchies in the context of electronic commerce
Proceedings of the 7th international conference on Electronic commerce - ICEC '05, 2005According to the theory of Transaction Cost Economics, markets and hierarchies are two basic and alternative models of organization. In the environment of Electronic Commerce, markets and hierarchies have been transforming into Electronic markets (EMs) and Electronic Hierarchies (EHs).

Electron–electron coincidence spectroscopies at surfaces
Journal of Electron Spectroscopy and Related Phenomena, 2002In the past 20 years, a steadily increasing number of electron-electron coincidence experiments on atoms and molecules have contributed to a deeper understanding of electron-electron correlation effects. In more recent years this technique has been extended to the study of solid surfaces.

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.
