Role of quantum confinement in semiconductor-superconductor core-shell nanowires
Tudor Gabriel Dumitru, Anna Sitek, Gunnar Thorgilsson +3
This work is motivated by the experimentally observed coherence of the supercurrent in semiconductor nanowires covered by a half-shell metallic superconductor, which leads to flux…
Spin-orbit interaction in core-shell semiconductor-metal nanowires
Tudor-Gabriel Dumitru, Anna Sitek, Gunnar Thorgilsson +2
We study theoretically the spin-orbit interaction of electrons confined in a tubular semiconductor nanowire, between an inner semiconductor core and an outer metallic extra shell.…
Spin-orbit interaction in tubular prismatic nanowires
Anna Sitek, Sigurdur I. Erlingsson, Andrei Manolescu
We theoretically study the spin-orbit interaction in the outer regions of core-shell nanowires that can act as tubular, prismatic conductors. The polygonal cross section of these w…
Spin-orbit interaction in square core-shell nanowires
Anna Sitek, Tudor Gabriel Dumitru, Sigurdur I. Erlingsson +1
We theoretically investigate the spin-orbit interaction of electrons confined in the outer regions of square core-shell nanowires. The polygonal cross section leads to the accumula…
