Rotation-angle dependence of Raman spectra in CaCo₂As₂. (a) and (b) Raman spectra collected under parallel and cross polarization configurations respectively. (c) and (d) Intensity modulations with rotation angles in two configuration channels. The angles are the ones between a axis and polarization of incident light.
