| Research Abstract |
Ferroelectric is widely used for industry as a FeRAM, optical filters, piezoelectric devices and various sensors. A boundary between neighboring domains, namely, "domain-wall" has strong influences on the properties of ferroelectric. However, structure and functions of the domain-walls are not well understood due to the difficulty of characterization of domain-walls. In this study, we successfully fabricated artificial domain-walls using a bicrystal experiment. As a result, the structure and property of the ferroelectric domain-walls have been well characterized by scanning transmission electron microscopy and electric measurement systems.
