Electrical and optical properties of (110)-oriented YBa2Cu3O7 / (110)-oriented PrBa2(Cu0.8Ga0.2)3O7 heterostructure

ORAL

Abstract

We performed epitaxial growth of (110)-oriented YBa2Cu3O7 / (110)-oriented PrBa2(Cu0.8Ga0.2)3O7 heterostructure using pulsed laser based thin film deposition technique for the nanofabrication of Superconductor (S) / Insulator (I) / Superconductor (S) tunneling Josephson junction device which may operate with low cost and simple liquid nitrogen based cryogenic system and may provide high IcRn product (with Ic being the junction critical current and Rn the normal resistance). X-ray diffraction pattern (XRD) analysis, atomic force microscopy (AFM), electrical transport, and optical characterization studies were performed to check the orientation and thickness, surface morphology, critical temperature (TC), electrical resistivity, proximity effect, and optical properties of the heterostructure. Here, we present experimental results on structural, electrical transport, and optial properties of the heterostructure.
