NONLINEAR CURRENT OSCILLATIONS IN A JOSEPHSON JUNCTION WITH FRACTAL RADIOISOTOPE COMPOSITES
Journal Title: Metrology and Measurement Systems - Year 2008, Vol 15, Issue 3
Abstract
We present a new form of the Josephson junction with dielectric layer containing radioisotopic inclusions. The presence of additional generators of ionization in a semiconducting material (due to α - particles emitted by radioisotope inclusions) causes the essentially nonequilibrium dispersive characteristics of composite materials. Nonlinear current oscillations in such nonequilibrium Josephson junctions are investigated. It is worth noting that a Josephson junction with fractal layer acquires additional characteristics. Taking into account that the medium is a fractal one, the generalization of the oscillation equation by means of fractional integro-differential operators can be an adequate model of a tunnel junction in this case. An analysis of general modes of linear and nonlinear oscillations in a nonequilibrium fractal Josephson junction is carried out. Such electronic elements can be used for chaotic communication.
