Figure 3: The vibrational properties of TiS3 under hydrostatic pressure.

From: Unusual lattice vibration characteristics in whiskers of the pseudo-one-dimensional titanium trisulfide TiS3

Figure 3

(a) Optical photograph of the DAC under × 50 optical lens in the experiment. (b) Optical image of TiS3 loaded inside the DAC. Scale bar, 1 nm. (c) Raman spectra of TiS3 under increasing hydrostatic pressure up to 26.3 GPa; plots are offset for clarity. (d) A comparison between the Raman spectra of TiS3 before applying pressure and after releasing pressure from 26.3 GPa. (e) Raman peak position as a function of pressure. The excitation (E) and detection (D) polarization is in parallel to the b axis. The dependence can be described as ω (P)=ω0+(dω/dP)P. The ω0 and dω/dP values are also shown in Table 1.
