Towards an ab-axis giant proximity effect using ionic liquid gating

Abstract

In this

Thesis, novel charge induction mechanisms of ionic liquids are treated, tested

and experimented on complex oxides, in particular cuprates. We show that it is

possible to traverse the phase diagram of a cuprate, albeit electrochemically. This is in turn has been used in combination with advanced lithogragphic techniques to attempt to fabricate an in-plane Josephson junction. We point out that a long-range proximity effect is observed in a number of junctions. Possible connections to the Giant Proximity Effect are evaluated in the final chapter of the Thesis.
