Abstract

The project is within all-electric spintronics that promises a new paradigm for memory and logic fabrication in future micro- and nanoelectronics. The present project aims at systematic studies of spin polarization, spin localization and spin-dependent transport in low-dimensional semiconductor-based nanosystems with lateral spin-orbit coupling such as quantum point contacts (QPCs) and quantum wires (QWs) created in InAs/InAlAs and GaAs/AlGaAs heterostructures. QPCs spin polarizers and spin valves controlled by applied electric fields will be studied theoretically for real experimental conditions, i.e., for different types of self-consistent confinement, Coulomb and spin blockade, under the influence of random impurities.
