Self-stabilization of high frequency oscillations in semiconductor superlattices by time-delay autosynchronization
J. Schlesner, A. Amann, N. B. Janson +2
We present a novel scheme to stabilize high-frequency domain oscillations in semiconductor superlattices by a time-delayed feedback loop. Applying concepts from chaos control theor…

Chaotic front dynamics in semiconductor superlattices
A. Amann, J. Schlesner, A. Wacker +1
We analyze the dynamical evolution of the current and the charge density in a superlattice for fixed external dc voltage in the regime of self-sustained current oscillations, using…
