Abstract
We propose a microscopic model for the large double-layer capacitance and resistance jumps ΔCDL and ΔRDL which occur at T=Tc=112 K at the interface between the cuprate superconductor Tl2223 and an organic liquid electrolyte, as measured by Peck et al. The jumps are associated with changes in the superconductor-metal-insulator micromorphology of Josephson junctions which are weak links in the Tinkham-Blackstead network model of the high-temperature superconductive transition. Ion-channeling experiments strongly support the model explanation for the 10–30 % effects which are seen over ΔT≲0.5 K.
