Description
Elastic and stiffness moduli of vertically aligned single-crystal ZnO nanorods grown on Si(001) substrates were determined quantitatively by the surface Brillouin scattering technique. A longitudinal guided mode at 16 – 18 GHz enabled the exact determination of c11 from which c11 and c44 were measured to be 116 GPa and 42.4 GPa respectively, at room temperature.
