摘要：

We have measured the hole drift mobility in BaTiO3 parallel to the c axis between 25°C and 140°C by transient SCLC. μ ≅ 2-3.10-2 cm2/V sec at room temperature and increases with T up to 0.15 cm2/V sec at 130°C. Just above the Curie point (132°C) μ = 2.10-2cm2/V sec. By steady state SCLC we show the presence of a hole trap (density 3.1018/cm3) located at 0.35 eV above the valence band. © 1969.
