Abstract

The composition and valence state (and therefore superconductivity) of a superconducting material (10) is adjusted and maintained by the electrochemical addition or subtraction of an enhancement material from or to a donor or receptor control material (14) located in close proximity to the superconducting material (10). Where the superconducting material (10) is an oxide phase the valency is controlled by the electro-transport of oxygen to or from the material (14), by the application of electrochemical potential. Enhancement may occur through an ionic conductor (12) which may be a solid or liquid electrolyte. In one example oxygen is added through a solid electrolyte yttria zirconia, calciazirconia or of bismuth oxide containing strontium oxide, calcium oxide or lanthanum oxide. In other examples valency and therefore superconductivity is controlled by the transport of fluorine (F-) or copper (Cu+).
