Studies on pulse electrodeposition of high T-c superconducting Hg-1212 thin films
The co-deposition of Hg-Ba-Ca-Cu alloyed films was successfully carried out by the pulse electrodeposition technique for the first time. A pulsating potential with 25 Hz frequency and 50% duty cycle was used. Different processing parameters such as deposition potential, current density, deposition time were studied and optimized. These alloyed films were then electrochemically oxidized from IN KOH solution at room temperature to get superconducting HgBa2CaCu2O6+delta thin films. XRD and microstructural studies were carried out for structural characterization. The films, after electrochemical oxidation, were tested for their electrical properties and were found to show superconducting behavior below T-c = 104.7 K.
