phonon emission

phonon emission

[′fō‚nän i‚mish·ən]
(solid-state physics)
The production of a phonon in a crystal lattice, which may result from the interaction of other phonons via anharmonic lattice forces, from scattering of electrons in the lattice, or from scattering of x-rays or particles which bombard the crystal.

At higher electric field, inter-valley optical phonon emission dominates causing the drift velocity to saturate at around 0.
