摘要：

Within the quasiclassical Boltzmann-Bloch approach to nonlinear miniband transport in superlattices, elastic scattering is included in a relaxation-time approximation. Elastic scattering makes the problem truly three dimensional and leads in the regime of negative differential conductance to results that are qualitatively different from those of the quasi-one-dimensional models considered previously and compare favorably with recent experiments and balance-equation calculations.
