Exciton gas transport through nano-constrictions
Chao Xu, J. R. Leonard, C. J. Dorow +4
An indirect exciton is a bound state of an electron and a hole in spatially separated layers. Two-dimensional indirect excitons can be created optically in heterostructures contain…
High-mobility indirect excitons in wide single quantum well
C. J. Dorow, M. W. Hasling, D. J. Choksy +4
Indirect excitons (IXs) are bound pairs of electrons and holes confined in spatially separated layers. We present wide single quantum well (WSQW) heterostructures with high IX mobi…
Split-gate device for indirect excitons
C. J. Dorow, J. R. Leonard, M. M. Fogler +3
We present a concept and experimental proof of principle for split-gate devices for indirect excitons (IXs). The split-gate forms a narrow channel, a point contact, for IX current.…
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…
Control of excitons in multi-layer van der Waals heterostructures
E. V. Calman, C. J. Dorow, M. M. Fogler +4
We report an experimental study of excitons in a double quantum well van der Waals heterostructure made of atomically thin layers of \Mo* and hexagonal boron nitride (hBN). The emi…
Measurement of exciton correlations using electrostatic lattices
M. Remeika, J. R. Leonard, C. J. Dorow +4
We present a method for determining correlations in a gas of indirect excitons in a semiconductor quantum well structure. The method involves subjecting the excitons to a periodic…
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…
