摘要
Based on a two-band tight-binding model,the dynamics of electrons under the action of static electric fields with Markoffian dephasing is investigated.The effective scattering time is obtained under the conditions of long-time limit and small interband communication through a perturbative calculation,from which the signature of Zener resonances and relatively long time evolution behavior are predicted.
