Abstract

We present a high-precision experimental verification of the universality of f(α), the fractal dimension of the subset of the attractor with scaling index α, at the transition from quasiperiodicity to chaos with the golden-mean winding number. The experimental system is cooled extrinsic p-type Ge, which is voltage biased to produce a spatially dependent active oscillation.
