摘要: In this chapter we outline the theories that are usually employed for phonon transport in solids. particular, provide a detailed description of essential steps deriving lattice thermal conductivity expressions within single-mode relaxation-time approximation. Explicit expression various scattering rates, bulk and low-dimensional solids, have been provided. Numerical evaluation rates is using both Debye’s isotropic continuum scheme realistic Brillouin zone summation technique based upon application special wavevectors scheme. Results presented selected bulk, superlattice, nanostructed systems. Based on such results, briefly discuss concept engineering high-efficiency thermoelectric materials.
