Pulsed laser deposition of Bi2Sr2Ca1–xYxCu2O8+δ (Bi-22Y2) with x = 0, 0.30, and 0.49 on an MgO (100) substrate was conducted using a Q-switched 1064 nm Nd:YAG laser The laser-produced plasma (LPP) emission was collected during the deposition. Time-resolved optical emission spectroscopy reveals that the plasma plume consists of neutral atoms and ions. SEM images indicate that clusters of correct stoichiometry...
High Tc superconducting Bi2Sr2Ca1-xYxCu2O8+δ (Bi-22Y2) with 0.25≤x≤0.49 were deposited on MgO (100) by infrared (1064 nm) pulsed laser deposition with subsequent heat treatments. As- deposited films were partially melted and subsequently annealed in ambient air. The as-deposited films exhibit spheriodal morphology but maintain the stoichiometry of the target. After heat treatments steps, relatively...
