Electronic properties of quasi onedimensional quantum wire models under equal coupling strength superpositions of Rashba and Dresselhaus spinorbit interactions in the presence of an inplane magnetic field
Abstract
In this paper one deals with the theoretical derivation of energy bands and of related wavefunctions characterizing quasi 1D semiconductor heterostructures, such as InAs quantum wire models. Such models get characterized this time by equal coupling strength superpositions of Rashba and Dresselhaus spinorbit interactions of dimensionless magnitude a under the influence of inplane magnetic fields of magnitude B. We found that the orientations of the field can be selected by virtue of symmetry requirements. For this purpose one resorts to spin conservations, but alternative conditions providing sensible simplifications of the energyband formula can be reasonably accounted for. Besides the wavenumber k relying on the 1D electron, one deals with the spinlike s=±1 factors in the front of the square root term of the energy. Having obtained the spinorial wavefunction, opens the way to the derivation of spin precession effects. For this purpose one resorts to the projections of the wavenumber operator on complementary spin states. Such projections are responsible for related displacements proceeding along the Oxaxis. This results in a 2D rotation matrix providing both the precession angle as well as the precession axis.
