| Abstract: | The induced modulation of the exciton density in a system consisting of spatially separated layers of a two-dimensional electron
gas and indirect dipolar excitons is studied theoretically. In particular, it is shown that an external potential causes Friedel
oscillations in the density of excitons due to their interaction with electrons. Possibilities for experimental observation
of this effect are briefly discussed. |
