Abstract:

The report discusses the lattice component of thermal conductivity in metals, alloys, and semiconductors and the influence affecting it. Phonon scattering processes are described by a relaxation time. The lattice component is expressed in terms of the intrinsic electronic component of thermal conductivity. The residual thermal resistivity is also considered. The influence of the ideal or intrinsic electronic thermal resistivity and that of the residual thermal resistivity on the total thermal conductivity is discussed. A rather detailed discussion is given of the methods of separating the measured thermal conductivity into the electronic and lattice components. The intrinsic lattice component of thermal conductivity and influences affecting it are considered rather completely. A fairly exhaustive treatment of the effect of crystal imperfections on the lattice thermal conductivity is given. Author
