MOD-processed YBCO thin films prepared by chemically controlled precursor solution

화학적으로 제어된 전구체용액을 사용하여 MOD법으로 제조된 YBCO 박막

Solution-based MOD-TFA deposition technology of YBCO layers offers a route to low-cost YBCO coated conductors. Since the structures and properties of grown thin film by MOD process are strongly influenced by chemistry of precursor solution, the chemical modification of precursor solution for MOD process are important for improvement of the electrical properties of YBCO films. In this study, the precursor solution for MOD process are modified by chemical additives and solvents. The microstructure and texture of YBCO films grown by chemically modified precursor solution were characterized with SEM/EDS, XRD.
