Resonant Tunneling in a Polymer with Charge Injection Doping

Abstract

Abstract. It is shown that a supercurrent in disordered polymers placed between superconductor electrodes may be explained by resonant tunneling of Coopers pairs along polymer channels formed due to electrification effect. Polymer film thickness where supercurrent one may to observe depends on superconducting coherence length in superconductor. The more coherence length in superconductor electrode the more is a polymer film thickness where superconductor exists. Shapiro steps induced by microwave (f = 9.3 GHz) radiation correspond to a single Josephson junction.
