The derived multifractal dimension for the observed bifurcation sequence shows different characteristics for chaotic, quasiperiodic, and frequency-locked attractors. In the chaotic regime, strange attractors are observed. Even in the quasiperiodic regime, attractors with a certain degree of strangeness may exist. From the observed multifractal dimensions, the deterministic nature of the chaotic oscillations is clearly identified.4 p.application/pdfeng(c) The American Physical Society, 1999Caos (Teoria de sistemes)SemiconductorsSemiconductorsChaotic behavior in systemsMultifractal dimension of chaotic attractors in a driven semiconductor superlatticeinfo:eu-repo/semantics/article517050info:eu-repo/semantics/openAccess
