Collective excitations in quasi-one-dimensional electron systems under a magnetic field
(American Physical Society, 1993)A study of the magnetoplasmons of a cylindrical quasi-one-dimensional electron system is given in the presence of an axial magnetic field B. A two-subband system is considered and the dispersion relations for both intrasubband ... -
Dynamical screening effects in a coupled quasi-one-dimensional electron-phonon system
(Institute of Physics Publishing Ltd., 1995)A fully dynamical and finite-lempel'dture study of the electron momenhum relaxation rate and mean free path in a coupled system of electrons and bulk LO phonons in a quantum wire structure is presented. Electmn-electron ... -
Dynamical screening effects in hot-electron scattering from electron-hole plasma and LO-phonon modes in quantum wires
(Elsevier, 1996)We present a fully dynamical and finite temperature study of the hot-electron momentum relaxation rate and the power loss in a coupled system of electron-hole plasma and bulk LO-phonons in a quantum wire structure. ... -
Effect of cross-sectional geometry on the RPA plasmons of quantum wires
(Pergamon Press, 1994)The effect of cross-sectional geometry on both the intrasubband plasmon and intersubband plasmon of a quantum wire is investigated within a two-subband RPA scheme. Exact analytical electronic wavefunctions for circular, ... -
Magnetic-field dependence of low-temperature mobility in quasi-one-dimensional electron systems
(Institute of Physics Publishing Ltd., 1994)We study the mobility of a quasi-one-dimensional (Q1D) electron system in the presence of an axial magnetic field at low temperatures. We consider the mobility limits for remote-impurity scattering, homogeneous-background ... -
Screening effects on the confined and interface polarons in cylindrical quantum wires
(American Physical Society, 1996)We study the contribution of confined and interface phonons to the polaron energy in quantum-well wires. We use a dispersionless, macroscopic continuum model to describe the phonon confinement in quantum wires of circular ...
