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.
