We study transport of indirect excitons in GaAs/AlGaAs coupled quantum wells in linear lattices created by laterally modulated gate voltage. The localization-delocalization transition for transport across the lattice was observed with reducing lattice amplitude or increasing exciton density. The exciton interaction energy at the transition is close to the lattice amplitude. These results are consistent with the model, which attributes the localization-delocalization transition to the…

Interplay between periodicity and nonlinearity of indirect excitons in coupled quantum wells.
TLDR
It is shown that the model involving both attractive two-body and repulsive three-body interactions can lead to a natural account for the LDT of excitons across the lattice when reducing lattice amplitude or increasing particle density.
Hydrodynamics of indirect excitons in coupled quantum wells
This thesis comprises a theoretical study of the dynamics of indirect excitons in coupled quantum wells at low lattice temperatures. The results of numerical simulations of the exciton
Trapping interlayer excitons in van der Waals heterostructures by potential arrays
Transition metal dichalcogenide heterostructures can host interlayer excitons (IXs), which consist of electrons and holes spatially separated in different layers. IXs possess permanent dipoles and
Self-organization phenomena at exciton condensation in quantum wells in an inhomogeneous external potential
A theory of the separation of a system of indirect excitons into a condensed and a gaseous phases with the formation of regular patterns of alternating phases in inhomogeneous external fields is
Exciton effective mass enhancement in coupled quantum wells in electric and magnetic fields
We present a calculation of exciton states in semiconductor coupled quantum wells in the presence of electric and magnetic fields applied perpendicular to the QW plane. The exciton Schrodinger
Observation of Exciton Spin Transport
This chapter presents the observation of the spin transport of spatially indirect excitons in GaAs coupled quantum wells (CQW). The spin relaxation time of indirect excitons is orders of magnitude
Spin transport of excitons.
TLDR
This work reports on observation of the spin transport of spatially indirect excitons in GaAs/AlGaAs coupled quantum wells (CQW), which is achieved due to orders of magnitude enhancement of the exciton spin relaxation time in CQW with respect to conventional quantum wells.
