Charge rearrangement and screening in a quantum point contact
Silvia Lüscher, Lindsay S. Moore, Tomaz Rejec +3
Compressibility measurements, sensitive to charge rearrangements, are performed on a quantum point contact (QPC). Screening due to mobile charges in the QPC is quantitatively measu…
Conductance anomalies and the extended Anderson model for nearly perfect quantum wires
T. Rejec, A. Ramsak, J. H. Jefferson
Anomalies near the conductance threshold of nearly perfect semiconductor quantum wires are explained in terms of singlet and triplet resonances of conduction electrons with a singl…
Coulomb Blockade Resonances in Quantum Wires
T. Rejec, A. Ramsak, J. H. Jefferson
The conductance through a quantum wire of cylindrical cross section and a weak bulge is solved exactly for two electrons within the Landauer-Buettiker formalism. We show that this…
Effect of deconfinement on resonant transport in quantum wires
A. Ramsak, T. Rejec, J. H. Jefferson
The effect of deconfinement due to finite band offsets on transport through quantum wires with two constrictions is investigated. It is shown that the increase in resonance linewid…
