摘要：

We report on Brillouin light scattering investigations on chemical-vapor-deposited polycrystalline diamond films. Besides the longitudinal and two transverse acoustic bulk phonons, a Rayleigh surface mode is observed. From the bulk modes the elastic constants c11, c12, and c44 of 1062 +/- 74, 122 +/- 8, and 541 +/- 22 GPa, respectively, are determined exhibiting the characteristic values of natural diamond. The observed Rayleigh mode sound velocity of 10326 +/- 470 m/s is consistent with the (110) texture of the polycrystalline film and the determined elastic constants.
