Origin of the hysteresis in bilayer 2D systems in the quantum Hall regime
L. H. Ho, L. J. Taskinen, A. P. Micolich +3
The hysteresis observed in the magnetoresistance of bilayer 2D systems in the quantum Hall regime is generally attributed to the long time constant for charge transfer between the…
Electrometry using the quantum Hall effect in a bilayer 2D electron system
L. H. Ho, L. J. Taskinen, A. P. Micolich +3
We discuss the development of a sensitive electrometer that utilizes a two-dimensional electron gas (2DEG) in the quantum Hall regime. As a demonstration, we measure the evolution…
Observation of orientation- and -dependent Zeeman spin-splitting in hole quantum wires on (100)-oriented AlGaAs/GaAs heterostructures
J. C. H. Chen, O. Klochan, A. P. Micolich +6
We study the Zeeman spin-splitting in hole quantum wires oriented along the and crystallographic axes of a high mobility undoped (100)-oriented AlGaAs/GaAs he…
Ground-plane screening of Coulomb interactions in two-dimensional systems: How effectively can one two-dimensional system screen interactions in another?
L. H. Ho, A. P. Micolich, A. R. Hamilton +1
The use of a nearby metallic ground-plane to limit the range of the Coulomb interactions between carriers is a useful approach in studying the physics of two-dimensional (2D) syste…
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…
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…
