Spontaneous oscillations developing during low-temperature impact ionization breakdown in extrinsic germanium are looked at with respect to characteristic features of type-I intermittency

Spontaneous oscillations developing during low-temperature impact ionization breakdown in extrinsic germanium are looked at with respect to characteristic features of the type-I intermittent route to chaos. We have examined the scaling behavior of the mean laminar phase length upon varying the transverse magnetic field applied. Taking into account the distribution of the phase lengths, the return map of the oscillation maxima, and the prevailing reinjection probability, we present experimental evidence that type-I intermittency takes place in a spatially extended macroscopic system with self-generated dynam-1cs.
