 The basis of design of nanoionic devices is the creation of nanostructures with nanoionic parameter "λ" / "L" ~ 1, where "L" is the size of device structure, and "λ" is the characteristic size of specific region where the property of fast ionic transport is realized.“Possibilities to influence on these specific regions < λ > in a controllable manner may appear in short sized devices”.Ion - electronic hybrid devices should be considered as a step on a way to the future nanoelectronics-nanoionics (nanoelionics) that was first proposed in 1996.
