✦ Synopsis

The generalized transport equations derived in 1 for the coupled electron-phonon system are solved in the collision-dominated regime. The solution is obtained without making any relaxationtime-approximation.

The sound velocity and the ultrasonic attenuation are calculated with the help of the equation of motion for the lattice deformation. In particular, we derive the lowest order anharmonic contribution to the sound velocity. For the attenuation, the contributions due to the viscous properties of the phonon gas and the electron gas are considered. We also take into account the thermoelastic damping.
