Abstract

Abstract – Superconductors are materials that offer zero electric resistance below their transition temperature. Bi2Sr2CaCu2O8 (Bi-2212) is a high-temperature superconductor with many promising applications in micro-electronic devices, magnetic shielding, and high-current carrying wires. Smooth films are needed to utilize Bi-2212 for device applications. We deposited Bi-2212 films using electrophoretic deposition (EPD). The films underwent rapid thermal annealing (RTA) in air and a cold bath. All films were post-annealed. Analyses of the x-ray diffraction (XRD) and scanning electron microscopy (SEM) data reveal that cold-quenched samples maintain their crystallinity while providing a more featureless surface. However, resistance versus temperature measurements show that cold quenching degrades the superconducting properties of the films.
