From: Structural phase transitions in Bi2Se3 under high pressure
Typical Rietveld refinement results of Bi2Se3 under (a) 4.6, (b) 14.1 and (c) 81.2 GPa. The experimental and simulated data were symbolled with black solid sphere and red line. The solid short vertical lines show the positions of the allowed Bragg reflections for Bi2Se3 and Au. The difference between the observed and the fitted XRD patterns were shown with a line at the bottom of the diffraction peaks.
