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…
Aharonov-Bohm rings with strong spin-orbit interaction: the role of sample-specific properties
Fabrizio Nichele, Yashar Komijani, Szymon Hennel +6
We present low-temperature transport experiments on Aharonov-Bohm (AB) rings fabricated from two-dimensional hole gases in p-type GaAs/AlGaAs heterostructures. Highly visible h/e (…
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…
Hanle effect in (In,Ga)As quantum dots: Role of nuclear spin fluctuations
M. S. Kuznetsova, K. Flisinski, I. Ya. Gerlovin +7
The role of nuclear spin fluctuations in the dynamic polarization of nuclear spins by electrons is investigated in (In,Ga)As quantum dots. The photoluminescence polarization under…
Counting statistics of hole transfer in a p-type GaAs quantum dot with dense excitation spectrum
Y. Komijani, T. Choi, F. Nichele +4
Low-temperature transport experiments on a p-type GaAs quantum dot capacitively coupled to a quantum point contact are presented. The time-averaged as well as time-resolved detecti…
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…
