Phys. Rev. E 68, 066208 (2003) [5 pages]Self-stabilization of high-frequency oscillations in semiconductor superlattices by time-delay autosynchronizationSee Also: Publisher's Note Received 21 March 2003; revised 17 September 2003; published 24 December 2003; publisher error corrected 26 January 2004 We present a scheme to stabilize high-frequency domain oscillations in semiconductor superlattices by a time-delayed feedback loop. Applying concepts from chaos control theory we propose to control the spatiotemporal dynamics of fronts of accumulation and depletion layers which are generated at the emitter and may collide and annihilate during their transit, and thereby suppress chaos. The proposed method only requires the feedback of internal global electrical variables, viz., current and voltage, which makes the practical implementation very easy. © 2003 The American Physical Society URL:
