Electromagnetic field emitted by core-shell semiconductor nanowires driven by an alternating current
Miguel Urbaneja Torres, Kristjan Ottar Klausen, Anna Sitek +3
We consider tubular nanowires with a polygonal cross-section. In this geometry the lowest energy states are separated in two sets, one of corner and one of side-localized states, r…
Transverse polarization light scattering in tubular semiconductor nanowires
Miguel Urbaneja Torres, Anna Sitek, Andrei Manolescu
We carry out numerical calculations of the scattering cross section of tubular semiconductor nanocylinders in the optical range. The scattering is investigated for the transversal…
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…
Radiated fields by polygonal core-shell nanowires
Miguel Urbaneja Torres, Anna Sitek, Vidar Gudmundsson +1
We calculate the electromagnetic field radiated by tubular nanowires with prismatic geometry and infinite length. The polygonal geometry has implications on the electronic localiza…
Controlled Coulomb effects in core-shell quantum rings
Anna Sitek, Miguel Urbaneja Torres, Kristinn Torfason +2
We analyse theoretically the possibilities of contactless control of in-gap states formed by a pair of electrons confined in a triangular quantum ring. The in-gap states are corner…
