Phonon Optics and Phonon Propagation in Semiconductors
Science, 1981Recent experiments involving the propagation of extremely high frequency, short-wavelength acoustic phonons in semiconductors are described. Such phonons, which play an important role in thermal energy transport and nonradiative recombination processes, can be used as sensitive microscopic probes of electronic, defect, and interface states.

Phonon-Phonon Interaction: Thermal Properties
1978The theory of lattice vibrations treated in Section 3.3 was restricted to the harmonic approximation. The potential energy of a lattice ion was expanded in powers of the displacements of the ions from their equilibrium positions, and the expansion was terminated after the first nonvanishing (quadratic) term.
