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…
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…
Localization-Delocalization Transition of Indirect Excitons in Lateral Electrostatic Lattices
M. Remeika, J. C. Graves, A. T. Hammack +5
We study transport of indirect excitons in GaAs/AlGaAs coupled quantum wells in linear lattices created by laterally modulated gate voltage. The localization-delocalization transit…
Statistical electron excitation in a double quantum dot induced by two independent quantum point contacts
U. Gasser, S. Gustavsson, B. Küng +4
We investigate experimentally the influence of current flow through two independent quantum point contacts to a nearby double quantum dot realized in a GaAs-AlGaAs heterostructure.…
