摘要：
The drift of degenerate 2D electrons in the channel of the heterojunction potential well is considered. In a quantizing magnetic field B, the electrons scan the defects of the heteroboundary, which perturb their momentum and energy equilibrium state (T, TD0). The stationary nonequilibrium state (T, TD*) is attained by electron-phonon relaxation in energy and momentum. The experimentally observed nonlinear dependence TD(T) is explained by the admixture of deformation acoustic phonons to the interaction of 2D electrons with piezoelectric phonons.
