The statistical equilibrium of phonons in the presence of a temperature gradient is investigated, and a general formula for the thermal conductivity of dielectric solids is obtained. This is applied to quartz glass, giving good agreement with values observed by Berman (1951), and to crystals. Comparison between theory and experiment are made for alkali-halides and quartz, and conclusions are drawn about the defects in neutron-irradiated quartz.

The High Temperature Thermal Conductivity of Semiconductor Alloys

A theory of the high temperature lattice thermal conductivity of semiconducting alloys is described in which normal processes are taken into account by the use of Callaway's method. This theory is in

A theoretical study of the temperature dependence of the thermal conductivity of polymers

The problem of heat conduction through polymers has been studied considering phonons as the chief carriers of heat. The presence of intermediate-range order, the orientational mismatch among the

Theoretical relationships and experimental data concerning thermal conductivity for a number of oxide materials have been compared over a wide temperature range. Deviations from the basic

Thermal conduction in glasses and polymers at low temperatures

Phonon scattering in amorphous solids due to anharmonic forces and structural disorder has been investigated. It is found that although anharmonic scattering persists to lower temperatures, when

An Explanation for the Plateau in the Thermal Conductivity of Non‐Crystalline Solids

The tunnelling-states model is applied to the thermal conductivity of non-crystalline materials. It is shown that the presence of a quadratic term in the energy dependence of the density of tunneling

Lattice Thermal Conduction Mechanism in Solids

The theory of lattice thermal conductivity of nonmetallic solids is presented. After discussing the fundamental issues, the kinetic-theory expression for the conductivity, based on the concept of

Thermal Conductivity of Solids at Low Temperatures

The most important mechanisms of heat transfer in solids are transfer by the lattice waves and transfer by the conduction electrons, and consequently the materials to be studied are broadly divided

Longitudinal phonons and high-temperature heat conduction in germanium

Using the relaxation time approach, the authors present a new analysis of phonon conductivity which shows that at high temperature (T> theta D, the Debye temperature), the longitudinal phonons are
