摘要：
A model for charge transport in photoexcited undoped semiconductor superlattices is proposed and analyzed. Under dc voltage bias, self-sustained oscillations of the current due to repeated homogeneous nucleation of pairs of charge dipole waves inside the sample, followed by wave splitting and motion in opposite directions are among the numerical solutions of the model.
