ABSTRACT
We have analyzed spatio-temporal current patterns and current–voltage characteristics of negative-effective-mass (NEM) p[sup +]pp[sup +] diodes driven by dc bias and terahertz (THz) electromagnetic radiation. Interesting nonlinear dynamics are presented, including current synchronization, frequency doubling, and transition to chaos. Discussions of suppressing possible chaos in NEM semiconductor devices are included. © 2001 American Institute of Physics.
