Abstract
The Callaway model has been applied to investigate the effect of (1) vibrating dislocation scattering, (2) static dislocation scattering, and (3) point-defect scattering of phonons on the thermal conductivity of deformed LiF crystals. It is found that the point-defect scattering of phonons does not produce any appreciable thermal resistance but that the other two scattering processes have a very strong influence on the thermal conductivity. The correction term due to three-phonon normal processes is also found to be significant.
