The following navigation utilizes arrow, enter, escape, and space bar key commands. Left and right arrows move through main tier links and expand / close menus in sub tiers. Up and Down arrows will open main tier menus and toggle through sub tier links. Enter and space open menus and escape closes them as well. Tab will move on to the next part of the site rather than go through menu items.

We performed epitaxial thin film deposition of a heterostructure of (110)-oriented YBa2Cu3O7 Superconductor (S) and (110)-oriented PrBa2(Cu0.8Ga0.2)3O7 electrical insulator (I) using a pulsed laser-based thin film deposition technique for the nanofabrication of an S-I-S tunneling Josephson junction device. This device may operate with a simple low-cost liquid nitrogen-based cryogenic system and has potential applications in superconducting quantum interference device based bio-magnetic sensors, quantum computing, and high-frequency detectors. X-ray diffraction measurement, atomic force microscopy, and low-temperature electrical resistivity measurement were performed to study the structural and electrical transport properties of the heterostructure. Here, we discuss our process for the deposition of a high-quality heterostructure and present our experimental results on the structural and electrical transport properties of the heterostructure.
