Utilizing scanning tunneling microscopy/spectroscopy to investigate the interface, the spatial resolved spectroscopy can be obtained. The analysis of spectroscopy reveals the superconducting behavior in YBCO. The results provide the evolution of superconductivity as a function of distance from the interface, and the behavior influenced by the ferroelectric domain wall.釔鋇銅氧鐵酸鉍超導體多鐵電性YBa2Cu3O7&not-xBiFeO3superconductormultiferroic
