Figure 2

XRD patterns collected in (a) I(Q) style and (b) I(2θ) style at selected pressures for Sb2S3 with an incident wavelength λ = 0.6199 Å. The peaks marked as arrows, asterisks, solid triangles, and solid circles are the diffraction peaks for the emerging phases II, III, IV and V, respectively. The pattern at the top was observed at ambient pressure after releasing pressure.
