Time Periodic Behavior of Multiband Superlattices in Static Electric Fields
arXiv:cond-mat/9512045 · doi:10.1103/PhysRevB.53.4834
Abstract
We use an analytic perturbation expansion for the two-band system of tight binding electrons to discuss Bloch oscillations and Zener tunneling within this model. We make comparison with recent numerical results and predict analytically the frequency of radiation expected from Zener tunneling, including its disappearance, as a function of the system parameters.
