Intermittency route to chaos and broadband high-frequency generation in semiconductor superlattice coupled to external resonator
journal contribution
posted on 2015-10-15, 13:12 authored by Alexander E. Hramov, V.V. Makarov, V.A. Maximenko, Alexey A. Koronovskii, Alexander BalanovAlexander BalanovWe investigate the onset of broadband microwave chaos in the miniband semiconductor superlattice coupled to an external resonator. Our analysis shows that the transition to chaos, which is confirmed by calculation of Lyapunov exponents, is associated with the intermittency scenario. The evolution of the laminar phases and the corresponding Poincare maps with variation of a supercriticality parameter suggest that the observed dynamics can be classified as type I intermittency. We study the spatiotemporal patterns of the charge concentration and discuss how the frequency band of the chaotic current oscillations in semiconductor superlattice depends on the voltage applied.
