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…
0.7 Structure and Zero Bias Anomaly in Ballistic Hole Quantum Wires
R. Danneau, O. Klochan, W. R. Clarke +6
We study the anomalous conductance plateau around and the zero-bias anomaly in ballistic hole quantum wires with respect to in-plane magnetic fields applied par…
Ballistic transport in induced one-dimensional hole systems
O. Klochan, W. R. Clarke, R. Danneau +5
We have fabricated and studied a ballistic one-dimensional p-type quantum wire using an undoped AlGaAs/GaAs heterostructure. The absence of modulation doping eliminates remote ioni…
Anisotropic Zeeman splitting in ballistic one-dimensional hole systems
R. Danneau, O. Klochan, W. R. Clarke +7
We have studied the effect of an in-plane magnetic field B on a one-dimensional hole system in the ballistic regime created by surface gate confinement. We observed clearly the lif…
Zeeman splitting in ballistic hole quantum wires
R. Danneau, O. Klochan, W. R. Clarke +7
We have studied the Zeeman splitting in ballistic hole quantum wires formed in a (311)A quantum well by surface gate confinement. Transport measurements clearly show lifting of the…
Conductance quantization and the 0.7x2e2/h conductance anomaly in one-dimensional hole systems
R. Danneau, W. R. Clarke, O. Klochan +5
We have studied ballistic transport in a 1D channel formed using surface gate techniques on a back-gated, high-mobility, bilayer 2D hole system. At millikelvin temperatures, robust…
