摘要：
Previous studies have shown that high-quality Bi2Sr2CaCu2O8+delta (Bi-2212) films can be grown via sedimentation with subsequent post heat treatment [1]. However as the films were made thinner, relaxation and island formation occurs. To address the problem we added 10% KCl in the sediment to aid in the melting of the Bi-2212 with subsequent melt-quenching and annealing. The resulting film has a highly c-oriented Bi-2212 crystal structure, has smooth surface, and uniform substrate coverage. The thickness of the film ranges from 490 nm - 540nm. The highest J(c) that was achieved is 3579.54 A/cm(2) at 30K, with T-c-onset - 85.1K. (C) 2013 The Authors. Published by Elsevier B.V.
