Microscopic theory of the influence of dipole superparamagnetics (type <beta-CD<FeSO_4>>) on current flow in semiconductor layered structures (type GaSe, InSe)

Abstract

A statistical approach to description of the charge carrier transfer processes in hybrid nanostructures taking into account electromagnetic fields is proposed using the method of the nonequilibrium statistical operator Zubarev. Generalized transfer equations are obtained, which describe non-Markov processes of charge transfer in the system taking into account magnetic and polarization processes under the influence of external and induced internal electromagnetic fields. Weakly nonequilibrium charge transfer processes in nanostructures are considered, and a nonequilibrium statistical operator is obtained, by means of which the magneto-diffusion transfer equations for electrons in layered nanostructures are obtained. A generalized Cattaneo-type diffusion equation in time fractional derivatives is obtained for electrons with a characteristic relaxation time and a generalized model is proposed that takes into account the complexity of relaxation electro-magnetic diffusion processes for electrons in layered nanostructures.

Kinetic description of ion transport in the system "ionic solution – porous environment"

“…Another aspect of research is related to the ionic conductivity of ionic solutions in porous and layered structures, which is important in connection with the anomalous behavior of ion diffusion and polarization effects [2,14,[20][21][22][23]. In particular, theoretical studies of electrodiffusion processes of ion transfer in systems are relevant "electrolyte -electrode" [4,5,14,[24][25][26][27][28][29][30][31] and associated with the need to describe nonequilibrium processes of intercalation-deintercalation of ions, and with the need for a theory suitable for practical application for forecasting and management these processes. Problems in the description of electrode processes are connected, first of all, as with the superficial phenomena at the interface "electrolyte -electrode", where complex processes of adsorption, desorption, diffusion, and in the middle of the electrodes (porous, layered in structure), where complex processes of association, dissociation between ions, their anomalous (sub or super) diffusion due to complex interaction with the structure of the electrode, which in turn are associated with problems of charge accumulation on electrodes in batteries.…”
