A circuit analysis of an in situ tunable radio-frequency quantum point contact
Thomas Müller, Theodore Choi, Sarah Hellmüller +3
A detailed analysis of the tunability of a radio-frequency quantum point contact setup using a C-LCR circuit is presented. We calculate how the series capacitance influences resona…
Counting statistics in an InAs nanowire quantum dot with a vertically coupled charge detector
Theodore Choi, Thomas Ihn, Silke Schön +1
A gate-defined quantum dot in an InAs nanowire is fabricated on top of a quantum point contact realized in a two-dimensional electron gas. The strong coupling between these two qua…
Noise-induced spectral shift measured in a Double Quantum Dot
Bruno Küng, Simon Gustavsson, Theodore Choi +6
We measure the shot noise of a quantum point-contact using a capacitively coupled InAs double quantum dot as an on-chip sensor. Our measurement signals are the (bidirectional) inte…
Spin-orbit interaction and spin relaxation in a two-dimensional electron gas
M. Studer, S. Schön, K. Ensslin +1
Using time-resolved Faraday rotation, the drift-induced spin-orbit Field of a two-dimensional electron gas in an InGaAs quantum well is measured. Including measurements of the elec…
Measuring current by counting electrons in a nanowire quantum dot
S. Gustavsson, I. Shorubalko, R. Leturcq +2
We measure current by counting single electrons tunneling through an InAs nanowire quantum dot. The charge detector is realized by fabricating a quantum point contact in close vici…
