Abstract
Brillouin scattering measurements carried out on a thin film of C70 deposited on a Si(1 0 0) substrate show modes at 4.8 and 25 GHz due to the surface Rayleigh wave and the bulk longitudinal acoustic mode, respectively, the corresponding modes for C60 being found at 4.3 and 30 GHz. Based on the Brillouin data, the values of the bulk, shear and Young's moduli of C70 are found to be 11.3, 3.2 and 8.7 GPa, respectively (the corresponding values for C60 are 14.9, 4.7 and 12.7 GPa). Poisson's ratios for C70 and C60 are comparable, the values being 0.37 and 0.36, respectively.
