Abstract:
The absorption and amplification of ultrasound in semiconductors with high mobility in the presence of an external electric field E satisfying the conditionseE«q? ¯ , eEt_r«p ¯ (q -wave sound vector, t_r - pulse relaxation time, ? ¯, p ¯- is the characteristic value of the electron energy and momentum). It is shown that the absorption and amplification coefficients of sound essentially from the mechanisms of electron scattering.
