Abstract
The thermal conductivity of freestanding films of -Ge has been measured in the temperature range 0.03-5 K. The results indicate scattering of phonons from tunneling systems, cylindrical voids, and boundaries. The first two mechanisms are correlated with density, the strongest scattering occurring in the samples of lowest density.
