Abstract

CaCu₃Ti₄O₁₂ thin films were prepared on Pt/Ti/SiO₂/Si substrate by a sol-gel method. A ferroelectric hysteresis loop was obtained at room temperature for amorphous CaCu ₃Ti₄O₁₂ thin film. The ferroelectric characteristic of amorphous CaCu₃Ti₄O₁₂ thin film was corroborated by the observation of piezoresponse force microscopy. The result indicates that there exists correlated intrinsic electric dipole moment in amorphous CaCu₃Ti₄O₁₂ thin film, and the origin of ferroelectricity in amorphous CaCu₃Ti₄O ₁₂ thin film is also discussed.
