Phonon confinement and screening effects on the polaron energy in quantum wires
(Institute of Physics Publishing Ltd., 1995)
We study the contribution of confined 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 square cross section. ...
Simplified calculations of band-gap renormalization in quantum-wells
(Academic Press, 1996)
Non-linear optical properties of photoexcited semiconductor quantum-wells are of interest because of their opto-electronic device application possibilities. Many-body interactions of the optically created electrons and ...
Spin correlations in a quasi-one-dimensional electron gas
(Elsevier BV, 1996)
We study the spin correlations in a quasi-one-dimensional electron gas within the self-consistent-field approximation (SCFA). Electrons confined in a parabolic potential restricted to have free motion in one space dimension, ...
Collective modes in a quasi-one-dimensional, two-component electron liquid
(Pergamon Press, 1994)
Under favorable conditions, a new collective mode besides the usual plasmons may exist in degenerate electron-hole liquids. We calculate the dispersion and damping of this new mode (called the acoustic plasmon mode) in a ...
