Coulomb scattering lifetime of a two-dimensional electron gas.
Motivated by a recent tunneling experiment in a double quantum-well system, which reports an anomalously enhanced electronic scattering rate in a clean two-dimensional electron gas, we calculate the inelastic quasiparticle lifetime due to electron-electron interaction in a single loop dynamically screened Coulomb interaction within the random-phase-approximation. We obtain excellent quantitativ...
متن کاملHybrid Simulation of Scattering Distribution in Cone Beam CT
This paper presents a hybrid simulator for the fast calculation of x-ray projections. Uncollided radiations are determined with a ray-driven method whereas the scattering signal is partitioned into single and multiple scattering, respectively estimated with an accelerated deterministic method and a coarse Monte Carlo simulation. The simulator takes into account the full acquisition chain, from ...
متن کاملMonte Carlo simulation of remote-Coulomb-scattering-limited mobility in metal–oxide–semiconductor transistors
An improved theory for remote-charge-scattering-limited mobility in silicon inversion layers is developed. The model takes into account the effects of image charges, screening, inversion layer quantization, the contribution of different subbands, oxide thickness, the actual distribution of charged centers inside the structure, the actual distribution of carriers in the inversion layer, the corr...
متن کاملCoulomb scattering rate of a multisubband Q 1 D electron gas
In this work, the Coulomb scattering lifetimes of electrons in two coupled quantum wires have been studied by calculating the quasiparticle self-energy within a multisubband model of quasi-one-dimensional (Q1D) electron system. We consider two strongly coupled quantum wires with two occupied subbands. The intrasubband and intersubband inelastic scattering rates are caculated for electrons in di...
متن کاملScattering in the PT -symmetric Coulomb potential
Scattering on the PT -symmetric Coulomb potential is studied along a Ushaped trajectory circumventing the origin in the complex x plane from below. This trajectory reflects PT symmetry, sets the appropriate boundary conditions for bound states and also allows the restoration of the correct sign of the energy eigenvalues. Scattering states are composed from the two linearly independent solutions...
