Study of elastic properties of n-ZnSe single crystals by Brillouin scattering

Values of the elastic constants C1, C12 and C of the n- ZnSe single crystals with different free carrier concentration were studied using Brillouin light scattering method. It has been shown that the results obtained from Brillouin scattering study are in good agreement with the data obtained earlier from Raman scattering experiment. We also present the influence of the annealing procedure on the velocity of the elastic waves propagating in (1 10) and (1 1 1) planes for n-ZnSe single crystals. The large effect of the annealing procedure of the n-ZnSe single crystals in liquid zinc on their elastic properties has been discussed using theory proposed by Martin.
