Determining the stability and activation energy of Si acceptors in AlGaAs using quantum interference in an open hole quantum dot
D. J. Carrad, A. M. Burke, O. Klochan +6
We fabricated an etched hole quantum dot in a Si-doped (311)A AlGaAs/GaAs heterostructure to study disorder effects via magnetoconductance fluctuations (MCF) at millikelvin tempera…
Scaling of the Kondo zero bias peak in a hole quantum dot at finite temperatures
O. Klochan, A. P. Micolich, A. R. Hamilton +5
We have measured the zero bias peak in differential conductance in a hole quantum dot. We have scaled the experimental data with applied bias and compared to real time renormalizat…
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…
The Impact of Small-Angle Scattering on Ballistic Transport in Quantum Dots
A. M. See, I. Pilgrim, B. C. Scannell +10
Disorder increasingly affects performance as electronic devices are reduced in size. The ionized dopants used to populate a device with electrons are particularly problematic, lead…
Ultra-shallow quantum dots in an undoped GaAs/AlGaAs 2D electron gas
W. Y. Mak, F. Sfigakis, K. Das Gupta +7
We report quantum dots fabricated on very shallow 2-dimensional electron gases, only 30 nm below the surface, in undoped GaAs/AlGaAs heterostructures grown by molecular beam epitax…
Observation of the Kondo Effect in a Spin-3/2 Hole Quantum Dot
O. Klochan, A. P. Micolich, A. R. Hamilton +3
We report the observation of Kondo physics in a spin- 3/2 hole quantum dot. The dot is formed close to pinch-off in a hole quantum wire defined in an undoped AlGaAs/GaAs heterostru…
