摘要:

本文给出了含里德堡激子的Cu $_2$ O量子阱在任意场强均匀电场中的光学函数的理论计算结果。在能量区域分别考虑了离散激子态和连续态的外电场垂直和平行于量子阱平面的两种构型。借助于实密度矩阵方法,推导出量子阱电光函数的解析表达式,计算了激发能低于带隙能时的吸收谱。

英文摘要:

We present theoretical results of the calculations of optical functions for Cu$_2$O quantum well (QW) with Rydberg excitons in an external homogeneous electric field of an arbitrary field strength. Two configurations of an external electric field perpendicular and parallel to the QW planes are considered in the energetic region for discrete excitonic states and continuum states. With the help of the real density matrix approach, which enables the derivation of the analytical expressions for the QW electro-optical functions, absorption spectra are calculated for the case of the excitation energy below the gap energy.
