Abstract

With the use of a lattice-dynamical model which reproduces observed phonon dispersion curves very accurately, the isotope scattering of near-zone-boundary acoustic phonons in Ge is investigated theoretically. We show that the lattice dispersion which becomes appreciable in the THz-frequency region leads to the phonon relaxation time that decreases more rapidly than ${\ensuremath{\omega}}^{\ensuremath{-}4}$. This deviation from the ${\ensuremath{\omega}}^{\ensuremath{-}4}$ dependence (the ${\ensuremath{\omega}}^{\ensuremath{-}4}$ behavior is predicted by the continuum elasticity theory) amounts to about 20% at 1 THz and is enhanced heavily at the zone boundaries. Calculations are based on the lowest-order perturbation theory. Higherorder corrections are estimated as well and shown to be negligibly small.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
