Probing e-e interactions in a periodic array of GaAs quantum wires
Y. Jompol, C. J. B. Ford, I. Farrer +5
We present the results of non-linear tunnelling spectroscopy between an array of independent quantum wires and an adjacent two-dimensional electron gas (2DEG) in a double-quantum-w…
Observation of a two-dimensional spin-lattice in non-magnetic semiconductor heterostructures
Christoph Siegert, Arindam Ghosh, Michael Pepper +2
Tunable magnetic interactions in high-mobility nonmagnetic semiconductor heterostructures are centrally important to spin-based quantum technologies. Conventionally, this requires…
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…
Spontaneous current generation in gated nanostructures
D. W. Horsell, A. K. Savchenko, Y. M. Galperin +3
We have observed an unusual dc current spontaneously generated in the conducting channel of a short-gated GaAs transistor. The magnitude and direction of this current critically de…
