Coulomb-Blockade directional coupler
P. Pingue, V. Piazza, F. Beltram +3
A tunable directional coupler based on Coulomb Blockade effect is presented. Two electron waveguides are coupled by a quantum dot to an injector waveguide. Electron confinement is…
Unusual conductance collapse in one-dimensional quantum structures
KJ Thomas, DL Sawkey, M Pepper +4
We report an unusual insulating state in one-dimensional quantum wires with a non-uniform confinement potential. The wires consist of a series of closely spaced split gates in high…
Evolution of the bilayer nu = 1 quantum Hall state under charge imbalance
W. R. Clarke, A. P. Micolich, A. R. Hamilton +5
We use high-mobility bilayer hole systems with negligible tunneling to examine how the bilayer nu = 1 quantum Hall state evolves as charge is transferred from one layer to the othe…
Non-invasive detection of the evolution of the charge states of a double dot system
A. W. Rushforth, C. G. Smith, M. D. Godfrey +3
Coupled quantum dots are potential candidates for qubit systems in quantum computing. We use a non-invasive voltage probe to study the evolution of a coupled dot system from a situ…
