Abstract
The thermal conductivity of a borosilicate glass has been measured in the temperature range 0.05-50 K. The samples contained well-defined holes to provide a source of phonon scattering. The results are consistent with the predictions of the Debye model using experimentally measured sound velocities. The results also indicate that thermal transport at temperatures below ≈ 30 K is provided by low-frequency phonons having a characteristic temperature ≲ 3 K.Keywords
