Let us call this the first ordering of the atomic layers. Alternatively, in the successive ionizations of a given atom, the ...
WebNew scientific direction — nanoionics of advanced superionic conductors (ASICs) was proposed. Nanosystems of solid state ionics were divided onto two classes differing by an opposite influence of crystal structure defects on the ionic conductivity σi (energy activationE): I) nanosystems on the base compounds with initial small σi (large values …
