New analytical formulas for the electronic stopping power and the energy loss straggling of low velocity extended charge projectiles in the degenerate electron gas are calculated within the dielectric function method. The stopping and straggling effective charges Zeff of a projectile were analysed. They are found to differ one from the other and to depend on the electron gas density rs, on the ...

The gas discharge and photo-luminance properties of a planar lighting source featuring highly uniform light emission and mercury-free design were studied. The current density-voltage characteristics and the associated gas discharge of the devices operating with the values of the ratio of electric field to gas pressure (E/p) between 4.3 kV/Torr-cm and 35.7 kV/Torr-cm indicate that the width of t...

Large KrF amplifiers use electron beams to excite the laser gas. By necessity, the diode and laser cavity must be isolated by a mechanical barrier; an electron beam diode operates in vacuum, while the laser cavity may be filled with amagats of gas. Isolation is typically accomplished by a metal foil of low mass density which is mechanically supported by a structure having multiple open slots se...

Abstract The thermodynamic properties of electron gas under the extreme conditions high temperature, matter density, and/or a strong magnetic field largely determine behavior in upper layers neutron stars and accretion columns magnetized binary systems. A these objects makes motion electrons across essentially quantum. possible degeneracy relativism are also important. When studying onto magnet...

Recent advances in submicrometer technology have made it possible to confine the two-dimensional electron gas into high-mobility semiconductor heterostructures. Such structure with a lattice of electrondepleted circular obstacles are called quantum antidot lattices, or quantum Lorentz gas systems. By using the semiclassical scattering theory, we show that quantum interference in finite-size ope...

Collective and single-particle spin-flip excitations of a two-dimensional electron gas in a semimagnetic Cd1−xMnxTe quantum well are observed by resonant Raman scattering. Application of a magnetic field splits the spin-subbands and a spin-polarization is induced in the electron gas. Above some critical field, a collective spin-flip mode, which disperses with in-plane wave vector, dominates the...

Search for Majorana fermions renewed interest in semiconductor-superconductor interfaces, while a quest for higher-order non-Abelian excitations demands formation of superconducting contacts to materials with fractionalized excitations, such as a two-dimensional electron gas in a fractional quantum Hall regime. Here we report induced superconductivity in high-mobility two-dimensional electron g...

A recently developed quasi two-dimensional exact-exchange formalism within the framework of Density Functional Theory has been applied to a strongly inhomogeneous interacting electron gas, and the results were compared with state-of-the-art Variational Quantum Monte Carlo (VMC) numerical simulations for a three-dimensional electron gas under a strong external potential. The VMC results, extreme...
