Abstract:
:We report studies of [Formula: see text]-dependent Landé g-factor, performed by both continuous media approximation [Formula: see text] method, and atomistic tight-binding [Formula: see text] approach. We propose an effective, mesoscopic model for InAs that we are able to successfully compare with atomistic calculations, for both very small and very large nanostructures, with a number of atoms reaching over 60 million. Finally, for nanostructure dimensions corresponding to near-zero g-factor we report electron spin states anti-crossing as a function of system size, despite no shape-anisotropy nor strain effects included, and merely due to breaking of atomistic symmetry of cation/anion planes constituting the system.
