Nonlinear Oscillations and Chaos in CdS Single Crystals under Temperature‐Electric Instability Conditions

Abstract

Low-frequency chaotic and complex regular oscillations of photocurrent and temperature in CdS single crystals occurring at constant applied voltage and illumination are investigated. Routes from periodicity to chaos are studied. Explanation of the complex behaviour is presented on base of a rate-equation model of temperature-electric instability in semiconductors with two types of electron trap levels.
