Abstract

An estimate is made of the thermal resistivity arising from phonon scattering by the static strain fields of edge-dislocation dipoles in lithium flouride, the dynamic scattering from which was recently studied by Kneezel and Granato (1980). The strain field scattering is shown to be increasingly important as the temperature increases above 2 K. This is consistent with the results of Kneezel and Granato. The static and dynamic mechanisms are shown to complement each other so that the total scattering from dipoles is consistent with the experimental data of Roth and Anderson (1979) from 0.1 to 9 K.
