Zener quantum dot spin filter in a carbon nanotube
D. Gunlycke, J. H. Jefferson, S. W. D. Bailey +3
We predict and analyze a novel spin filter in semiconducting carbon nanotubes. By using local electrostatic gates, the conduction and valence bands can be modulated to form a doubl…
A Hartree-Fock Study of Charge Redistribution in a 2D Mesoscopic Structure
A. Kambili, H. Fehrmann, C. J. Lambert +1
In this paper, we investigate the ground state of two-dimensional disordered cylinders which contain spinless, interacting electrons using the Hartree-Fock approximation. Calculati…
Interacting electrons in a nearly straight quantum wire
T. Rejec, A. Ramsak, J. H. Jefferson
The conductance threshold of a clean nearly straight quantum wire in which a single electron is bound is studied. This exhibits spin-dependent conductance anomalies on the rising e…
Anomalies in the conduction edge of quantum wires
T. Rejec, A. Ramsak, J. H. Jefferson
We study the conductance threshold of clean nearly straight quantum wires in which an electron is bound. We show that such a system exhibits spin-dependent conductance structures o…
Magnetic properties of a two-electron quantum dot
C. E. Creffield, J. H. Jefferson, S. Sarkar +1
The low-energy eigenstates of two interacting electrons in a square quantum dot in a magnetic field are determined by numerical diagonalization. In the strong correlation regime, t…
Suppression of Giant Magnetoresistance by a superconducting contact
F. Taddei, S. Sanvito, J. H. Jefferson +1
We predict that current perpendicular to the plane (CPP) giant magnetoresistance (GMR) in a phase-coherent magnetic multilayer is suppressed when one of the contacts is superconduc…
