Limit cycle induced frequency locking in self-sustained current oscillations of superlattices
Z. Z. Sun, H. T. He, J. N. Wang +2
The ac response of self-sustained current oscillations (SSCOs) in GaAs/AlAs superlattices (SLs) is derived based on the deformation of a limit cycle under an external ac driving fo…

Limit cycle theory of temporal current self-oscillations in sequential tunneling of superlattices
X. R. Wang, Z. Z. Sun, S. Q. Duan +1
A unified theory of the temporal current self-oscillations is presented. We establish these oscillations as the manifestations of limit cycles, around unstable steady-state solutio…
