Using a tunable quantum wire to measure the large out-of-plane spin splitting of quasi two-dimensional holes in a GaAs nanostructure
A. Srinivasan, L. A. Yeoh, O. Klochan +6
The out-of-plane g-factor g_perp for quasi-2D holes in a (100) GaAs heterostructure is studied using a variable width quantum wire. A direct measurement of the Zeeman splitting is…
Piezoelectric rotator for studying quantum effects in semiconductor nanostructures at high magnetic fields and low temperatures
L. A. Yeoh, A. Srinivasan, T. P. Martin +3
We report the design and development of a piezoelectric sample rotation system, and its integration into an Oxford Instruments Kelvinox 100 dilution refrigerator, for orientation-d…
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…
The role of background impurities in the single particle relaxation lifetime of a two-dimensional electron gas
S. J. MacLeod, K. Chan, T. P. Martin +5
We re-examine the quantum tau_q and transport tau_t scattering lifetimes due to background impurities in two-dimensional systems. We show that the well-known logarithmic divergence…
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…
