Rydberg excitons are, with their ultrastrong mutual interactions, giant optical nonlinearities, and very high sensitivity to external fields, promising for applications in quantum sensing nonlinear optics at the single-photon level. To design it is necessary know how other excited states relax lower-lying exciton states. Here, we present photoluminescence excitation spectroscopy as a method pro...
In this study we analyze the transmission spectrum of a thin plate Cuprous Oxide in range absorption yellow exciton states with coherent transfer matrix method. We demonstrate that, contrast to usual analysis using Beer's law, which turns out be rather good approximation only spectral region high principal quantum numbers, consistent quantitative description over whole under consideration is po...
Broader context Cuprous oxide (Cu2O) is a candidate material for photovoltaic and photoelectrochemical device applications due to its suitable band gap and low processing cost. Furthermore, due to the natural abundance of its component elements in the atmosphere and crust, it is a candidate for terawatt scale solar energy production. Given the electronic band gap of Cu2O is 2.1 eV, the detailed...
