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.…
Conductance features of core-shell nanowires determined by the internal geometry
Miguel Urbaneja Torres, Anna Sitek, Sigurdur I. Erlingsson +3
We consider electrons in tubular nanowires with prismatic geometry and infinite length. Such a model corresponds to a core-shell nanowire with an insulating core and a conductive s…
Multi-domain electromagnetic absorption of triangular quantum rings
Anna Sitek, Gunnar Thorgilsson, Vidar Gudmundsson +1
We present a theoretical study of the unielectronic energy spectra, electron localization, and optical absorption of triangular core-shell quantum rings. We show how these properti…
Recursive Green's function method for multi-terminal nanostructures
G. Thorgilsson, G. Viktorsson, S. I. Erlingsson
We present and review an efficient method to calculate the retarded Green's function in multi-terminal nanostructures; which is needed in order to calculate the conductance through…
Rashba spin orbit interaction in a quantum wire superlattice
Gunnar Thorgilsson, J. Carlos Egues, Daniel Loss +1
In this work we study the effects of a longitudinal periodic potential on a parabolic quantum wire defined in a two-dimensional electron gas with Rashba spin-orbit interaction. For…
