We have studied the transfer dynamics of excitons between large, monolayer-flat islands in single quantum wells, using subpicosecond luminescence spectroscopy. We show that the excitons transfer from the narrow to the wide regions of the well in ∼250 ps.

    We report the first studies of exciton luminescence spectra from asymmetric double quantum wells (DQWs) of very similar width. The DQWs were of GaAs/AlGaAs and the differences in widths of the coupled wells were one or two monolayers. The coupled direct and indirect exciton states anticross with...

    The theory of exciton condensation is given in two-dimensional systems under the suggestion that condensation occurs in real space and condensed phase arises as a result of an attractive interaction between excitons. Due to the finite value of exciton lifetime, the sizes of exciton condensed...
