We also plotted the experimentally measured (in purple) and calculated (in black) values of phonon energies at Г level of those nine phonon modes, for a comparison, in Supplementary Fig. 12. In Table one, the 1st column displays All those modes�?energies from various polarized Raman environment. Every single benefit is the averages of peak fit
