Excitonic switches at 100 K temperatures
G. Grosso, J. Graves, A. T. Hammack +4
Photonic and optoelectronic devices may offer the opportunity to realize efficient signal processing at speeds higher than in conventional electronic devices. Switches form the bui…
Collection of indirect excitons in a diamond-shaped electrostatic trap
A. A. High, A. K. Thomas, G. Grosso +7
We report on the principle and realization of a new trap for excitons -- the diamond electrostatic trap -- which uses a single electrode to create a confining potential for exciton…
Electron counting in quantum dots
S. Gustavsson, R. Leturcq, M. Studer +5
We use time-resolved charge detection techniques to investigate single-electron tunneling in semiconductor quantum dots. The ability to detect individual charges in real-time makes…
Bandgap and Band Offsets Determination of Semiconductor Heterostructures using Three-terminal Ballistic Carrier Spectroscopy
Wei Yi, Hong Lu, Yong Huang +5
Utilizing three-terminal tunnel emission of ballistic electrons and holes, we have developed a method to self-consistently measure the bandgap of semiconductors and band discontinu…
Universality of Bias- and Temperature-induced Dephasing in Ballistic Electronic Interferometers
Y. Yamauchi, M. Hashisaka, S. Nakamura +8
We performed a transport measurement in a ballistic Aharonov-Bohm ring and a Fabry-Perot type interferometer. In both cases we found that the interference signal is reversed at a c…
Gate-controlled spin-orbit interaction in a parabolic GaAs/AlGaAs quantum well
M. Studer, G. Salis, K. Ensslin +2
We study the tunability of the spin-orbit interaction in a two-dimensional electron gas with a front and a back gate electrode by monitoring the spin precession frequency of drifti…
