Abstract

Dynamic chaos evolution scenarios of the development of a Kadomtsev-Nedospasov instability in the electron-hole plasma in germanium at 77 and 300 K have been studied experimentally in external electric and magnetic fields at high control parameters. The development of a spatio-temporal chaotic state in the system has been analysed using probe measurements along a sample. It is shown that several attractors, with their own dimensions and power characteristics, may exist simultaneously in the same sample. Scenarios have been found leading to chaos through period doubling, quasi-periodicity and intermittency, depending on the parametric space; transitions of the order-chaos-order type have also been observed.
