Abstract
Thermostimulated exoelectron emission has been employed for studying the phase transition temperature and defect structure of dielectric and semiconducting BaTiO3 ceramics. It was found that reduction of BaTiO3 ceramic leads to dramatic changes in the TSEE spectra. The increase of current carrier concentration results in appearance of two new TSEE peaks in 420–590 K region. TSEE peaks corresponding to ferroelectric Curie point T c have been observed both for dielectric and semiconducting samples.Keywords
