偶极激子杂化结构中的量子点

Quantum Dot in a Hybrid Structure with Dipolar Excitons

M. M. Mahmoodian, A. V. Chaplik

摘要:

位于二维偶极激子系统附近的量子点中的电子态受到电子-激子相互作用引起的激子密度涨落的扰动。这导致量子点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。在本工作中,两个最低的量子点能级的移动被发现在正常状态的激子系统和玻色-爱因斯坦凝聚(BEC)制度。

英文摘要:

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.
