Fig. 2: Low-frequency Raman spectroscopy to 28.3 GPa.
From: Phase transition mechanism and bandgap engineering of Sb2S3 at gigapascal pressures
a Raman spectra of compressed Sb2S3 in the range of 0–400 cm−1 wavelength. The asterisk peaks were not traceable thus not assigned to specific modes. b Evolution of each Raman mode over pressure. The frequency of peak has maximum uncertainty of 5 cm−1. Mode displacements are derived from the first-principles simulation at low pressure. Inl interlayer.
