Low-Temperature Thermal Brillouin Scattering in Fused Silica and Borosilicate Glass
Abstract
Brillouin scattering experiments have been performed between 1.7 and 300 K in glasses to demonstrate the existence of thermal phonons. The theoretically expected linear temperature dependence of the Brillouin peak intensities has been observed.
