摘要：

Stability of both wavefronts and solitary waves under current bias is studied for a standard rate equation model of electrical conduction in extrinsic semiconductors which includes effects of field-dependent impurity impact ionization. We prove that monotonic traveling wavefronts are linearly stable whereas solitary space charge waves are unstable on the infinite one-dimensional line.
