论文摘要
在这项研究中，我们分析了使用相干传递矩阵方法在黄色激子态吸收范围内的一块氧化热氧化物的透射光谱。我们证明，与使用Beer定律进行的常规分析相反，仅在高主量子数的光谱区域中，这是一个相当好的近似值，在考虑到正在考虑的整个光谱范围内的一致定量描述是可能的。这不仅导致了Rydberg激子状态的新的，更准确的参数，而且还导致了间接过渡的优势。此外，结果对光激发后电子孔对密度的测定产生了影响。
In this study we analyze the transmission spectrum of a thin plate of Cuprous Oxide in the range of the absorption of the yellow exciton states with the coherent transfer matrix method. We demonstrate that, in contrast to the usual analysis using Beer's law, which turns out to be a rather good approximation only in the spectral region of high principal quantum numbers, a consistent quantitative description over the whole spectral range under consideration is possible. This leads to new and more accurate parameters not only for the Rydberg exciton states, but also for the strengths of indirect transitions. Furthermore, the results have consequences on the determination of the density of electron-hole pairs after optical excitation.
