摘要：
A nonmonotonous temperature dependence of the electron quantum relaxation time is found. The results are interpreted, taking into account the competition between the intrasubband and intersubband electron-electron interaction channels. The experimental nonlinear τq (T) and TD (T) dependences are explained by the appearance of an additional channel of two-dimensional (2D) electron scattering by deformation acoustic phonons under interaction with piezoacoustic phonons.
