We report resonant Brillouin scattering results in CdSe. Enhancements in Brillouin scattering have been observed at both the I2 bound exciton and the free exciton. As a result of the spatial dispersion of the exciton-polariton, the Brillouin frequencies vary with the polariton energy. From this variation of the Brillouin frequencies, we deduced the following parameters in CdSe: transverse exciton frequency =14713 cm-1, splitting between longitudinal and transverse exciton frequencies = 4cm-1 and exciton effective mass (perpendicular to the c-axis) =0.40 times free electron mass. The Brillouin linewidths were found to vary with polariton energies in qualitative agreement with the theory of Brenig, Zeyher and Birman. © 1978.
