理论分析的电子能谱和磁化的应变InxGa 1-xAs/GaAs自组装量子环（SAQR）的电子进行与现实的参数，确定从横截面扫描隧道显微镜表征的纳米结构。在我们的SAQR模型中，研究了库仑相互作用对SAQR中激子能谱的影响以及对光跃迁几率的影响。(c)2008 WILEY-VCH Verlag GmbH & Co. KGaA，魏因海姆
Theoretical analysis of the electron energy spectrum and the magnetization of an electron in a strained InxGa1-xAs/GaAs self-assembled quantum ring (SAQR) is performed with realistic Parameters, determined from the cross-sectional scanning-tunneling microscopy characterization of that nano-structure. The effects Of the Coulomb interaction oil the energy spectrum of oil exciton in a SAQR as well as on the Optical-transition probabilities are studied within our model of a SAQR.
