Abstract
The nonequilibrium phonon energy due to deformation interactions with hot electrons is determined. This energy depends on the lifetime of phonons with fixed momentum. Lifetime for phonons scattered by electrons and by macroscopic and microscopic impurities are calculated using the Keldysh diagram technique.
