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…
Interplay between Aharonov-Bohm and Altshuler-Aronov-Spivak oscillations in phase-pure GaAs/InAs core/shell nanowires of different lengths
Farah Basarić, Kaiwen Wang, Tudor-Gabriel Dumitru +7
In GaAs/InAs core/shell nanowires, comprising a tubular conducting shell, interference phenomena observed under an axial field and originating from closed-loop states encircling th…
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 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…
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…
Aharonov-Bohm and Altshuler-Aronov-Spivak oscillations in the quasi-ballistic regime in phase-pure GaAs/InAs core/shell nanowires
Farah Basarić, Vladan Brajović, Gerrit Behner +10
The realization of various qubit systems based on high-quality hybrid superconducting quantum devices, is often achieved using semiconductor nanowires. For such hybrid devices, a g…
Optimal field-free magnetization switching via spin-orbit torque on the surface of a topological insulator
Ivan P. Miranda, Grzegorz J. Kwiatkowski, Cecilia M. Holmqvist +6
We present an optimal field-free protocol for current-induced switching of a perpendicularly magnetized ferromagnetic insulator nanoelement on the surface of a topological insulato…
Anisotropic transport properties in prismatic topological insulator nanowires
Hallmann Oskar Gestsson, Andrei Manolescu, Jens H. Bardarson +1
The surface of a three dimensional topological insulator (TI) hosts surface states whose properties are determined by a Dirac-like equation. The electronic system on the surface of…
Charge and heat currents in prismatic tubular nanowires
Hadi Rezaie Heris, Kristjan Ottar Klausen, Anna Sitek +2
We calculate electronic charge and heat transport in tubular nanowires generated by a temperature gradient or a chemical potential bias. These nanowires correspond to semiconductor…
