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…
Time--delay autosynchronization of the spatio-temporal dynamics in resonant tunneling diodes
J. Unkelbach, A. Amann, W. Just +1
The double barrier resonant tunneling diode exhibits complex spatio-temporal patterns including low-dimensional chaos when operated in an active external circuit. We demonstrate ho…
A hybrid model for chaotic front dynamics: From semiconductors to water tanks
A. Amann, K. Peters, U. Parlitz +2
We present a general method for studying front propagation in nonlinear systems with a global constraint in the language of hybrid tank models. The method is illustrated in the cas…
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…
