| Summary: | 碩士 === 大葉大學 === 電機工程學系 === 98 === We studied the anisotropic properties of High-Tc superconducting YBa2Cu3O7-δ (YBCO) films grown on SrTiO3 (110) substrates. The YBCO films were characterized by X-Ray diffraction, the atomic force microscope (AFM), and resistivity measurement. We researched the upper critical field (Hc2) and the pinning potential energy (U) in the different direction. The critical temperature (Tc) was decreasing with the field was increasing. As the anisotropic angle increased, the plot of Hc2 vs Tc curves of films showed downward straight lines. The pinning potential energy was decresing the field was increasing.
