By changing the concentration of mobile charge carriers, applied electric fields influence the transport properties of high-T c superconductors in the superconducting state. Experimental studies of these effects are briefly reviewed.

It is argued that the new theory that combines the precursor BCS-like non-superconducting (SC) pairing and the Cooper-pair condensation into a superfluid Bose-liquid state is more plausible than the standard SC fluctuation approach in describing the distinctive features of the underdoped and overdoped high-Tc cuprates. We show that the scenarios for high-Tc superconductivity in these materials are quite different on the character of the Cooper-pair formation and SC phase transitions.

This paper shows that the pseudogap (PG) of Y123 and B2212 is caused by two-local- Cu ++-spin-mediated interaction (TLSMI) in the CuO 2 plane and that PG is a gap of quasiparticle excitation which breaks a Cooper pair without long-range phase coherence.

High Tc Cuprates

Taking the two-local-spin-mediated interaction (TLSMI) as the pair potential for the Cooper pair and considering the long-range phase coherence (LRPC), the empirical formula of T c versus hole doping is explained and the physical picture for the pseudogap and the gap in superconductive state is set up. The superconductivity in PrBa 2 Cu 3 O 7-δ and CuCl at high pressure and Fe 1-x S is discussed.
