Abstract

This study investigates the fabrication of In-doped Bi-2212 film samples using sedimentation deposition, exploring post-annealing times of 0, 20 minutes, and 30 hours. The research aims to assess the impact of post-annealing time variations on superconductivity. Results indicate that while it is possible to produce the Bi-2212 phase at reduced annealing temperatures, the crystallinity and grain quality of the films are critical for optimizing superconductivity. Enhanced superconducting response, evidenced by resistivity measurements, emphasizes the importance of precise annealing control. Longer annealing times, although commonly used, may not be suitable for time-sensitive applications. Despite variations in post-annealing time, all samples exhibit superconductivity, with T_c,onsetranging from 78K to 85K, consistent with XRD results.
