We also plotted the experimentally calculated (in red) and calculated (in black) values of phonon energies at Г level of these nine phonon modes, for the comparison, in Supplementary Fig. 12. In Table 1, the initial column exhibits These modes�?energies from unique polarized Raman environment. Each value would be the averages of peak fitting f
