摘要: The dispersion of higher‐order localized elastic modes gold layers on glass has been measured by Brillouin scattering. For layer thicknesses h≥100 A the sound velocities is well described continuum theory, whereas for h<100 deviations occur due to island formation. results yield a reliable, nondestructive method determine either constants and mass density or thickness thin supported metal layers.
