(a) Unpolarized Raman spectrum of MnPS3 collected at room temperature. (b) Polarized Raman spectra of MnPS3 at room temperature under Z ( XX ) Z ¯ (red line) and Z ( XY ) Z ¯ (blue line) scattering geometry. Inset: the XYZ/abc coordinates. (c) Intensity map of Raman spectra of MnPS3 under parallel polarization scattering geometry as a function of Raman shift and angle. (d) Same as (c), but under cross polarization geometry.
