Electron states in a quantum dot (QD) located near a 2D system of dipolar excitons are perturbed by fluctuations of the exciton density caused by the electron-exciton interaction. This results in the frequency changes of electron transitions in a QD. The frequency depends on the exciton density, as well as on the exciton gas phase state. In the present work, the shifts of the two lowest QD energy levels are found both in the normal state of the exciton system and for the Bose-Einstein condensation (BEC) regime.

具有偶极激子的混合结构中的量子点

位于偶极激子二维系统附近的量子点 (QD) 中的电子态受到由电子-激子相互作用引起的激子密度波动的干扰。这导致 QD 中电子跃迁的频率变化。频率取决于激子密度以及激子气相状态。在目前的工作中，在激子系统的正常状态和玻色-爱因斯坦凝聚 (BEC) 状态中都发现了两个最低 QD 能级的变化。
