Description

High-lying Rydberg states of Mott-Wannier excitons are receiving considerable interest due to the possibility of adding long-range interactions to the physics of excitons. In this work, we study Rydberg excitation in bulk synthetic cuprous oxide grown by the optical float zone technique and compare the result with natural samples. Figure 1 describes the visual characteristics of the two different crystals, and this data is recorded as four separate .JPG files. Figure 2 shows a comparison between the X-ray diffraction patterns where the incident beam was perpendicular the (100) crystal plane. The images are stored as two .PNG files. Figure 3 shows optical excitonic transmission spectra for the two materials. The raw data is stored as 4-column ASCII .TXT files, as well as the VEUSZ plots used the present the data. Figure 4 shows how the exciton spectra varies with at different positions across a radial cross section of the synthetic crystal. A visual image of the sample in-situ is stored as a .JPG file, and the raw data to generate the VEUSZ plot is stored as a 9-column ASCII .TXT file. Figure 5 describe some statistics about the spatial variation of the n=6 exciton peak. The raw data used to generate these histograms are stored as 3-column ASCII .TXT files, along with the VEUSZ plot used to present the data. Figure 6 compares the room temperature photoluminescensee for synthetic and gemstone samples. The raw data is stored as two 4-column ASCII .TXT files, along with the VEUSZ plot used to show the data. Figure 7 compares the high-resolution photoluminescence in the phonon replica region differs between synthetic and gemstone samples. The data is stored as a series of 2-column ASCII .TXT files, along with the VEUSZ plot used to present the data. Finally, figure 8 compares the mid-infrared absorption spectra for synthetic gemstone material at different temperature. The data is stored as a series of 2-column ASCII .TXT files, along with the relevant VEUSZ plot.
