Compressibility measurements of quasi-one-dimensional quantum wires
L. W. Smith, A. R. Hamilton, K. J. Thomas +5
We report measurements of the compressibility of a one-dimensional (1D) quantum wire, defined in the upper well of a GaAs/AlGaAs double quantum well heterostructure. A wire defined…
Row coupling in an interacting quasi-one-dimensional quantum wire investigated using transport measurements
L. W. Smith, W. K. Hew, K. J. Thomas +5
We study electron transport in quasi-one-dimensional wires at relatively weak electrostatic confinements, where the Coulomb interaction distorts the ground state, leading to the bi…
Incipient Formation of an Electron Lattice in a Weakly-Confined Quantum Wire
W. K. Hew, K. J. Thomas, M. Pepper +4
We study the low-temperature transport properties of 1D quantum wires as the confinement strength V_conf and the carrier density n_1D are varied using a combination of split gates…
Spin-Incoherent Transport in Quantum Wires
W. K. Hew, K. J. Thomas, M. Pepper +4
When a quantum wire is weakly confined, a conductance plateau appears at e^2/h with decreasing carrier density in zero magnetic field accompanied by a gradual suppression of the 2e…
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…
Interaction Effects at Crossings of Spin-Polarised One-Dimensional Subbands
A. C. Graham, K. J. Thomas, M. Pepper +3
We report conductance measurements of ballistic one-dimensional (1D) wires defined in GaAs/AlGaAs heterostructures in an in-plane magnetic field, B. When the Zeeman energy is equal…
