Resonance Transition of the Spatial Correlation Factor of Self-Generated Oscillations in the Postbreakdown Regime of p-Ge

Abstract

The linear correlation factor of spatially coupled nonlinear self-generated oscillations in the post-breakdown regime of p-Ge at 4.2 K is investigated. The observed results can be consistently explained in terms of a two-cell model of energy relaxation oscillations, which yields resonance transitions between correlated and anticorrelated oscillations. These are due to node-focus transitions of the fixed point of the passive cell which is slaved by the active cell. © 1989, Walter de Gruyter. All rights reserved.
