HOT-ELECTRONS UNDER QUANTIZATION CONDITIONS .2. THE BOLTZMANN-EQUATION

A general analysis of the Boltzmann equation is undertaken for the non -degenerate electrons in low-dimensional system interacting with bulk acoustic phonons. We derive expressions for symmetric and antisymmetri c collision operators for electrons confined by an arbitrary quantizin g potential. These expressions are universal and can be applied to thr ee-, two- or one-dimensional electron gases. As was shown in our previ ous paper (part I) the kinetics of the low-dimensional electron system is qualitatively different at low and high lattice temperatures due t o the kinematic peculiarities of the electron-acoustic-phonon interact ion. Here we present the Boltzmann equation to describe the non-equili brium electron distribution in low-dimensional electron systems under different external conditions which are of physical interest and which will be investigated in the following paper, part III.
