Abstract

The phonon-dispersion relation is one of the most fundamental properties of the solids. In particular, its knowledge is required for the explanation of the low-temperature thermal properties. Unfortunately, this relation can not be measured in glasses with neutron-scattering techniques because of the absence of a lattice periodicity. In addition, if the glass is only available as thin film, not even the sound velocity, the slope of the dispersion curve at the low-frequency end, can be determined by the standard ultrasonic techniques.
