Figure 1. (A) Schematic diagram of the peeling process; (B) Top-view images of the sample during the dissolution process over time within a 3 mm × 3 mm area, illustrating the continuous and uniform diffusion of the dissolved region from the periphery toward the central zone; (C) Photos of YBCO thin film samples after peeling. The film size after peeling remains almost the same, with integrity and no cracks. YBCO: YBa2Cu3O7.
