Bulk samples of high temperature superconductor Bi1.6Pb0.4Sr2Ca2Cu3-xZnxO10+δ system for x (0, 0.2, 0.4, 0.6, 0.8&1) were prepared by solid state reaction method. Pulse laser deposition (PLD) technique was used to prepare thin films from bulk target in vacuum chamber .The films were deposited on Si (111) substrate at 300oC. The distance between target and substrate was 5cm ablated by a double frequency with Q switched Nd: YaG pulse laser at 532 nm, pulse duration of about 7nsec, energy density (0.4-8) J/cm2, oxygen back ground pressure of 2*10-3 mbar and number of pulses 150 pulse. The samples were annealed at 820oC in vacuum furnace employing oxygen atmosphere with flow rate 2 lit/min. for 2 hrs. . X-ray diffractometer (XRD), Scanning electron microscopy (SEM) and atomic force microscopy (AFM) was used to investigate the structure and morphology of the prepared samples. The electrical properties (resistivity and transition temperature) were determined.
