Errata Erratum: phonon conductivity of doped germanium under uniaxial stress in the [110]direction [Phys. Rev. B 46, 7486 (1992)](1) In Table I, the correct value of rl should be 0.0335 X 10 cm jdyn.
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 the dominant heat carriers in germanium. The present result, which is a consequence of the effect of phonon dispersion on the Callaway integral for lattice thermal conductivity, is contrary to the general belief that transverse phonons carry heat at T> theta D. A qualitative justification has also been given for the three-phonon scattering parameters obtained.
The " d o n term in the Callaway model for phonon conductivity is separated inlo i s longiludinal and hnsverse pans in lhe presence of phonon dispersion. This will provide, for the 6rsi time, a realistic opponunity to speak about the total individual contributions of lhe phonons, of different polarizations, to the total phonon conductivity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
