抽象的。 微观理论用于研究光致发光 库仑效应和载流子-光子相关效应影响下的半导体量子点 超出 Hartree-Fock 水平。我们研究了最初激发的量子点的时间分辨发光的发射光谱和衰减特性。的影响 相关性包含在高达单双峰水平的簇扩展方案中。
Abstract. A microscopic theory is used to study photoluminescence of semiconductor quantum dots under the influence of Coulomb and carrier-photon correlation effects beyond the Hartree-Fock level. We investigate the emission spectrum and the decay properties of the time-resolved luminescence from initially excited quantum dots. The influence of the correlations is included within a cluster expansion scheme up to the singlet-doublet level.
