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…
A dynamic localization of 2D electrons at mesoscopic length scales
A. Ghosh, M. Pepper, H. E. Beere +1
We have investigated the local magneto-transport in high-quality 2D electron systems at low carrier densities. The positive magneto-resistance in perpendicular magnetic field in th…
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…
