Study of phonon-dislocation interaction in LiF and KCl crystals
A knowledge of dislocations is essential for an understanding of many of the physical and mechanical properties of crystalline solids. The low-temperature thermal conductivity of electrically insulating crystals is strongly influenced by dislocations. Measurement of the lattice thermal …

The scattering of thermal phonons by extended defects in dielectric crystals
The scattering of thermal phonons by extended defects in dielectric crystals has been observed through measurements of thermal conductivity and ballistic heat pulse propagation. The thermal conductivities of LiF and NaCt containing 500 low-angle grain boundaries per cm were measured in the range …
