TUNNELING INVESTIGATION OF THE IN-PLANE ANISOTROPY OF UNCONVENTIONAL SUPERCONDUCTORS
Abstract
The rare earth cuprate oxide family of unconventional superconductors has the potential to revolutionize superconducting electronics for numerous defense applications. The underlying physics of the electrical transport in thin films of these materials is not well-understood, particularly within the plane of the crystal where superconductivity is an order of magnitude stronger than that out-of-plane. The research in this proposal is targeted at increasing our knowledge regarding the physical mechanisms that govern these unconventional superconductors. We aim to use a novel tunnel technique, to conduct in-plane tunnel spectroscopy measurements in unconventional layered superconductors. Specifically, we will use nanowire Josephson junctions to directly probe electrical transport within the a-b plane of different high-Tc single crystal thin films. The information obtained will guide material synthesis to improve important properties for electronics, such as critical current, critical temperature, and material homogeneity.
