论文摘要
我们研究了带电杂质的静态,不相关的分布对铜氧化物cu $ _ {\ text {2}} $ o的限制激子光谱的影响。我们表明,Stark变化和电离率的统计分布导致Rydberg共振消失到明显的连续体中。由于旋转对称断裂而引起的其他吸收线的出现,以及空间不均匀的鲜明移位,导致对观察到的线形状的修改,这些形状与实验中观察到的变化一致。
We investigate the influence of a static, uncorrelated distribution of charged impurities on the spectrum of bound excitons in the copper oxide Cu$_{\text{2}}$O. We show that the statistical distribution of Stark shifts and ionisation rates leads to the vanishing of Rydberg resonances into an apparent continuum. The appearance of additional absorption lines due to the broken rotational symmetry, together with spatially inhomogeneous Stark shifts, leads to a modification of the observed line shapes that agree qualitatively with the changes observed in the experiment.
