The microwave induced resistance response of a high mobility 2DEG from the quasi-classical limit to the quantum Hall regime
S. A. Studenikin, M. Byszewski, D. K. Maude +6
Microwave induced resistance oscillations (MIROs) were studied experimentally over a very wide range of frequencies ranging from ~20 GHz up to ~4 THz, and from the quasi-classical…
Charge Sensing of an Artificial H2+ Molecule
M. Pioro-Ladriere, M. R. Abolfath, P. Zawadzki +4
We report charge detection studies of a lateral double quantum dot with controllable charge states and tunable tunnel coupling. Using an integrated electrometer, we characterize th…
The influence of the long-lived quantum Hall potential on the characteristics of quantum devices
M. Pioro-Ladriere, A. Usher, A. S. Sachrajda +5
Novel hysteretic effects are reported in magneto-transport experiments on lateral quantum devices. The effects are characterized by two vastly different relaxation times (minutes a…
The origin of switching noise in GaAs/AlGaAs lateral gated devices
M. Pioro-Ladrière, J. H. Davies, A. R. Long +7
We have studied the origin of switching (telegraph) noise at low temperature in lateral quantum structures defined electrostatically in GaAs/AlGaAs heterostructures by surface gate…
Detection of Single Electron Charging in an Individual InAs Quantum Dot by Noncontact Atomic Force Microscopy
Romain Stomp, Yoichi Miyahara, Sacha Schaer +6
Single electron charging in an individual InAs quantum dot was observed by electrostatic force measurements with an atomic force microscope (AFM). The resonant frequency shift and…
