We develop a theory of the low-temperature charge transfer between a superconductor and a hopping insulator. We show that the charge transfer is governed by the coherent two-electron -- Cooper pair conversion process, time reversal…

Charge redistribution at high-Tc superconductor interfaces and grain boundaries on the one hand is problematic for technological application. On the other hand, it gives rise to a great perspective for tailoring the local electronic states.…
