Mesoscopic and microscopic spin injection, spin precession, spin diffusion and spin transport in semiconductor nanostructures

摘要

Summary form only given. Presents the author's latest comprehensive theoretical investigations on spin kinetics of semiconductor quantum wells, quantum wires and quantum dots based on microscopic many-body and single particle approaches as well as mesoscopic approach under various conditions, such as temperature, external static electric and magnetic fields, THz radiations, confinement of the structure, strain etc. Both transient and steady-state transports are addressed. In addition to the cases near the equilibrium, spin kinetics far away from the equilibrium such as electrons of high spin polarization and/or electrons under strong electric field (hot electrons) is also discussed in detail. Good agreements with the available experiments are presented and many novel effects are predicted.
