From: Polarized Raman scattering study of kesterite type Cu2ZnSnS4 single crystals
Raman spectra of Cu2ZnSnS4 single crystals excited with laser line 532 nm (a) and 785 nm (b), close to resonant conditions.
Inset of figure (a) shows the fitting (red curve) of the experimental Raman spectra (black curve) with Lorentzian curves (green). Here the breaks on intensity scales were performed to show weaker peaks with lower intensity. Figures (c,d) represent the spectra measured at different polarization configurations. Here angles 0 deg and 90 deg correspond to 
and 
configurations, respectively.
