We also plotted the experimentally measured (in purple) and calculated (in black) values of phonon energies at Г stage of those 9 phonon modes, for your comparison, in Supplementary Fig. twelve. In Table 1, the main column displays These modes�?energies from various polarized Raman placing. Each price may be the averages of peak fitting result
