Radio-frequency reflectometry on large gated 2-dimensional systems
L. J. Taskinen, R. P. Starrett, T. P. Martin +5
We have embedded an AlGaAs/GaAs based, gated 2D hole system (2DHS) into an impedance transformer circuit, and show that by using radio-frequency reflectometry it is possible t…
Interplay between one-dimensional confinement and crystallographic anisotropy in ballistic hole quantum wires
O. Klochan, A. P. Micolich, L. H. Ho +3
We study the Zeeman splitting in induced ballistic 1D quantum wires aligned along the [233] and [011] axes of a high mobility (311)A undoped heterostructure. Our data shows that th…
Enhanced Zeeman splitting in Ga0.25In0.75As quantum point contacts
T. P. Martin, A. Szorkovszky, A. P. Micolich +5
The strength of the Zeeman splitting induced by an applied magnetic field is an important factor for the realization of spin-resolved transport in mesoscopic devices. We measure th…
The effect of screening long-range Coulomb interactions on the metallic behavior in two-dimensional hole systems
L. H. Ho, W. R. Clarke, A. P. Micolich +6
We have developed a technique utilizing a double quantum well heterostructure that allows us to study the effect of a nearby ground-plane on the metallic behavior in a GaAs two-dim…
