| 概要 |
Conductance decreasing with increasing temperature (T) above a characteristic T (T0) is found in the reverse-diode characteristics of metal contacts on strained BaTiO_3 epitaxial films. The conduction... mechanisms below and above T0 near the Curie temperature of the bulk BaTiO_3 are distinctly different. Marked similarities to these characteristics are found in the surface conduction on BaTiO_3 single crystal in a high vacuum. By comparing the observations with the positive temperature coefficient of resistance (PTCR) effect in ceramics, we suggest that the anomaly is regarded as a PTCR effect at metal/ferroelectric contact, and discuss the origin of the effect in thin films and single crystals.続きを見る
