Abstract

The analysis of Raman and Brillouin scattering spectra requires the knowledge of scattering tensors. Based on Birman's method, we compute the Clebsch-Gordan coefficients for first-order Raman and Brillouin scattering for Bi<sub>2</sub>Se<sub>3</sub> with D3d5 space group symmetry. The linear combination of Clebsch-Gordan coefficients gives the matrix elements of scattering tensors. Our predictions are useful for interpretation of experimental Raman and Brillouin scattering measurements.
