| 中文摘要 | A pyroelectric behavior was observed in CaCu3Ti4O12 films and the pyroelectric coefficient was measured to be 1.35x10(-7) C/cm(2) K for a film with thickness of 700 nm from 295 K to 340 K, larger than those of most pyroelectric materials. It was observed that the pyroelectric coefficient increased with the thickness of films from 300 to 700 nm. The origin of pyroelectric effect is proposed to depend on the distortion of the Ti-O octahedron due to the presence of Ti3+ ions. Comparing with the measurement result of an unpolarized film, our study strongly supports the interpretation of relaxor ferroelectric behavior in CaCu3Ti4O12. |
