  1. 1. Effects of the Spin-Orbit Interaction on Transport and Optical Properties of III-V Semiconductor Quantum Wells

    University dissertation from Division of Solid State Theory, Department of Physics, University of Lund, Sölvegatan 14A, SE-223 62 Lund

    Author : Vladimir Froltsov; Lunds universitet.; Lund University.; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; spin-orbit interaction; quantum well; III-V; Raman scattering; magnetoresistance; weak localization; spin distribution; magnetic field; Fysik; Physics; Fysicumarkivet A:2000:Froltsov; Halvledarfysik; Semiconductory physics; semiconductor;

    Abstract : Effects of the intrinsic electron spin-orbit interaction on transport and optical properties of III-V semiconductor quantum wells have been studied theoretically. It is shown that due to crystal anisotropy of this interaction, the weak localization magnetoresistance in a magnetic field parallel to interfaces is very sensitive to the epitaxy growth direction and also to the orientation of the magnetic field with respect to the crystal axes.
