THEORY OF CHARGE-TRANSFER AT THE HIGH-T-C SUPERCONDUCTOR ELECTROLYTE INTERFACE/

We discuss the kinetics of electrochemical process on the high-T-c sup erconducting electrodes dependent on the type of superconductivity. Th e existence of the hump of an appreciable height in the temperature de pendence of the current clearly points towards the BCS s-type supercon ductivity, involving a gap in the electronic spectrum. The height of t he hump should be much less in the case of the unconventional d-wave p airing, while the absence of the hump is a signal about the importance of pair-breaking processes typical of the strong-coupling theories or even about bipolaron (bosonic) mechanism. Low-temperature tails at th e current/temperature curve are also informative being determined by t he electronic states within the gap typical of the unconventional d-wa ve pairing.
