Transport of Indirect Excitons in High Magnetic Fields
Y. Y. Kuznetsova, C. J. Dorow, E. V. Calman +4
We present spatially- and spectrally-resolved photoluminescence measurements of indirect excitons in high magnetic fields. Long indirect exciton lifetimes give the opportunity to m…
Indirect excitons in a potential energy landscape created by a perforated electrode
C. J. Dorow, Y. Y. Kuznetsova, J. R. Leonard +5
We report on the principle and realization of an excitonic device: a ramp that directs the transport of indirect excitons down a potential energy gradient created by a perforated e…
Optical emission spectroscopy study of competing phases of electrons in the second Landau level
A. L. Levy, U. Wurstbauer, Y. Y. Kuznetsova +6
Quantum phases of electrons in the filling factor range are probed by the weak optical emission from the partially populated second Landau level and spin wave measu…
Fabrication of Artificial Graphene in a GaAs Quantum Heterostructure
Diego Scarabelli, Sheng Wang, Yuliya Y. Kuznetsova +7
The unusual electronic properties of graphene, which are a direct consequence of its two-dimensional (2D) honeycomb lattice, have attracted a great deal of attention in recent year…
Transport of indirect excitons in ZnO quantum wells
Yuliya Kuznetsova, Fedor Fedichkin, Peristera Andreakou +8
We report on spatially- and time-resolved emission measurements and observation of transport of indirect excitons in ZnO/MgZnO wide single quantum wells.
Stirring Potential for Indirect Excitons
M. W. Hasling, Y. Y. Kuznetsova, P. Andreakou +6
We demonstrate experimental proof of principle for a stirring potential for indirect excitons. The azimuthal wavelength of this stirring potential is set by the electrode periodici…
Optically Controlled Excitonic Transistor
P. Andreakou, S. V. Poltavtsev, J. R. Leonard +7
Optical control of exciton fluxes is realized for indirect excitons in a crossed-ramp excitonic device. The device demonstrates experimental proof of principle for all-optical exci…
Transport of Indirect Excitons in a Potential Energy Gradient
J. R. Leonard, M. Remeika, M. K. Chu +6
We realized a potential energy gradient - a ramp - for indirect excitons using a shaped electrode at constant voltage. We studied transport of indirect excitons along the ramp and…
Excitation Energy Dependence of the Exciton Inner Ring
Y. Y. Kuznetsova, J. R. Leonard, L. V. Butov +4
We report on the excitation energy dependence of the inner ring in the exciton emission pattern. The contrast of the inner ring is found to decrease with lowering excitation energy…
Electrostatic Conveyer for Excitons
A. G. Winbow, J. R. Leonard, M. Remeika +9
We report on the study of indirect excitons in moving lattices - conveyers created by a set of AC voltages applied to the electrodes on the sample surface. The wavelength of this m…
Spin transport of indirect excitons
J. R. Leonard, Y. Kuznetsova, Sen Yang +4
Spin transport of indirect excitons in GaAs/AlGaAs coupled quantum wells was observed by measuring the spatially resolved circular polarization of exciton emission. Exciton spin tr…
Spin transport of indirect excitons in GaAs coupled quantum wells
J. R. Leonard, Sen Yang, L. V. Butov +1
Spin transport of indirect excitons in GaAs/AlGaAs coupled quantum wells was observed by measuring the spatially resolved circular polarization of the exciton emission. The exciton…
