Inelastic electron and light scattering from the elementary electronic excitations in quantum wells: Zero magnetic field

  title={Inelastic electron and light scattering from the elementary electronic excitations in quantum wells: Zero magnetic field},
  author={Manvir S. Kushwaha},
  journal={AIP Advances},
The most fundamental approach to an understanding of electronic, optical, and transport phenomena which the condensed matter physics (of conventional as well as nonconventional systems) offers is generally founded on two experiments: the inelastic electron scattering and the inelastic light scattering. This work embarks on providing a systematic framework for the theory of inelastic electron scattering and of inelastic light scattering from the electronic excitations in GaAs/Ga1−x Al x As…

Inelastic electron and Raman scattering from the collective excitations in quantum wires: Zero magnetic field
The nanofabrication technology has taught us that an m-dimensional confining potential imposed upon an n-dimensional electron gas paves the way to a quasi-(n-m)-dimensional electron gas, with m ⩽ n
Observability of localized magnetoplasmons in quantum dots: Scrutinizing the eligibility of far-infrared, Raman, and electron-energy-loss spectroscopies
We investigate a one-component, quasi-zero dimensional, quantum plasma exposed to a parabolic potential and an applied magnetic field in the symmetric gauge. If the size of such a system as can be
The Quantum Pinch Effect in Semiconducting Quantum Wires: A Bird's-Eye View
Those who measure success with culmination do not seem to be aware that life is a journey not a destination. This spirit is best reflected in the unceasing failures in efforts for solving the problem
Plasmon mode coupling and depolarization shifts in AlGaAs/GaAs asymmetric step quantum wells with and without electric field
We investigate the plasmon mode coupling and depolarization shifts in AlGaAs/GaAs asymmetric step quantum wells (ASQWs) of the two-subband model with the Bohm–Pine’s random-phase approximation with
High mobility one- and two-dimensional electron systems in nanowire-based quantum heterostructures.
This work has introduced a novel type of core-shell nanowire heterostructures that incorporate modulation or remote doping and hence may lead to high-mobility electrons in GaAs/Al0.16Ga0.84As core-multishell nanowires grown on silicon.
Plasmons in spatially separated rolled-up electron-hole double-layer systems
Using the two-component random phase approximation, we report the collective mode spectrum of a quasi-one-dimensional spatially separated electron-hole double-layer system characterized by rolled-up


Theory of light scattering from electronic excitations in solids
SummaryThe effect of the periodic potential and the residual Coulomb interaction on the inelastic scattering of light from pure electronic excitations in solids has been investigated by using the

The dynamic surface response function g has been calculated for a quantum well, formed at the interface of two semiconductors and for a layered material, and Analytical closed-form expressions are obtained for the energy loss to the medium from an electron which moves along a classical trajectory close to the surface.
Resonant mechanisms of inelastic light scattering by low-dimensional electron gases.
The contribution of elementary excitations in low-dimensional electron gases to resonant inelastic light scattering is found to be determined by interband transitions involving states at specific
Resonant Raman scattering of quantum dots
We theoretically investigate the resonant Raman scattering of GaAs quantum dots. The electron system is treated within the time-dependent local-density approximation and the cross section is

Light Scattering by Electronic Excitations in n-Type GaAs-AlxGa1-xAs Superlattices
We present a theory of resonant inelastic light scattering by spin-density and charge-density excitations in modulation doped n -type GaAs–Al x Ga 1- x As superlattices. The scattering cross section
Large exchange interactions in the electron gas of GaAs quantum wells.
Inelastic-light-scattering measurements show that exchange Coulomb interactions in the two-dimensional electron gas of GaAs microstructures are more important than previously anticipated.
