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 tau(q)(T) and T-D(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.
