Magnetic semiconductor artificial atom with many particles: Thomas-Fermi model and ferromagnetic phases
Alexander O. Govorov
Many-particle electron states in semiconductor quantum dots with carrier-mediated ferromagnetism are studied theoretically within the self-consistent Boltzmann equation formalism.…
Spin-polarized reflection of electrons in a two-dimensional electron system
Hong Chen, J. J. Heremans, J. A. Peters +5
We present a method to create spin-polarized beams of ballistic electrons in a two-dimensional electron system in the presence of spin-orbit interaction. Scattering of a spin-unpol…
Magneto-optical properties of charged excitons in quantum dots
A. O. Govorov, C. Schulhauser, D. Haft +7
We present both experimental and theoretical results on the influence of a magnetic field on excitons in semiconductor quantum dots. We find a pronounced difference between the str…
Quantum wires and dots driven by intense surface acoustic waves and the quantum attenuation of sound in an electron plasma
A. O. Govorov, A. V. Kalameitsev, V. M. Kovalev
We develop a quantum theory of the nonlinear interaction between intense surface acoustic waves and electrons of a quantum well in the regime of moving quantum wires and dots. The…
