摘要：
We report the first experimental time-series analysis of the noisy acoustoelectric voltage oscillations in dc-current-driven InSb in a transverse magnetic field. We show that these irregular oscillations, originally thought to be random noise, are actually deterministic in origin. The fractal dimensions of typical oscillations are presented. We have observed deterministic chaos from 20 to 230 K. We find that the chaotic regime coincides with the freezeout of the intrinsic carriers, and that the threshold for chaos as a function of temperature scales with the magnetoresistance. © 1990 The American Physical Society.
