Conversion of YBCO Pellet into Single Layer Thin Film using Pulse Laser Deposition

Abstract

The Pulse laser deposition (PLD) is used to convert bulk YBCO Pellet to high-quality YBCO epitaxial film and superconducting transport properties of YBCO single layer has been investigated using surface techniques and four point probe method. The present study includes thin film fabrication via PLD, X-ray diffraction (XRD), Scanning electron microscopy and four point probe method. This study reveals the relationship between plume dynamics and quality of the single layer film based on the important parameter, such as background pressure, substrate temperature, plume size and film thickness. The plume dynamics role in fabricating high-quality layer and improving the superconducting properties of the single layer has been analysed.
