Most of the heat flow in semiconductors is carried by phonons (i.e.
quantized lattice vibrations). In the presence of a small temperature
gradient, phonon transport is also a problem in near-equilibrium
transport, and the techniques developed for electron transport can be
readily applied to phonons. This lecture is an introduction to phonon
transport. Key similarities and differences between electron and
phonon transport are discussed.
