Abstract

Thermal conductivity measurements on samples of p-Ge down to 50 mK indicate the presence of an approximately Gaussian distribution of resonant scattering frequencies which has a width Δ30 GHz. The data suggest that this is due to about half of the acceptors which are in distorted sites while the other half are relatively free from distortion. The "two-site" model reconciles disagreements in linewidth from different types of experiment. We obtain a value for Dua(dynamic)=4.1±0.4 eV.
