我们研究了GaN耦合量子点中的少粒子相互作用,并讨论了这些结构的内建场特性如何强烈地增强偶极-偶极和偶极-偶极相互作用。我们引入了一个半分析模型,允许快速和容易地估计的数量级的几个粒子的相互作用,其预测是接近10%以上的“确切”的结果。我们将我们的研究应用于全光读出设备的设计,该设备利用远程偶极-双极相互作用,也可用于监测量子点系统的电荷状态。
We study few-particle interactions in GaN-coupled quantum dots and discuss how the built-in field characteristic of these structures strongly reinforce dipole–dipole and dipole–monopole interactions. We introduce a semi-analytical model that allows for a rapid and easy estimate of the magnitude of few-particle interactions and whose predictions are closer than 10% to “exact” results. We apply our study to the design of an all-optical read-out device that exploits long-range dipole–monopole interactions and may be also used to monitor the charge status of a quantum dot system.
