Material fast transport in nano-crystals of (АВn–x)-type ionic compounds

Abstract

The effectiveness of material transport by the mechanism of single-file diffusion in comparison with the conventional mechanism of the classical diffusion of atoms is discussed. The conditions under which the single-file diffusion can provide fast mass transport are considered. The analysis and assessment made indicate that the diffusion of atoms along one-dimensional vacancy clusters formed in the (АВ_n–x)-type ion nano-crystals, may have a much faster mass transport compared to transport by the classical diffusion mechanism of atoms, which is defining for massive crystals.
