Abstract
- Temperature-dependent measurements using positron lifetime spectroscopy (PLS) were carried out to study various defects in polycrystalline donor doped BaTiO3 (BT) samples. Annealing under different donor-doping level of La and Y were performed. At high doping level, it was found that with increasing doping level the average lifetime increases. This is attributed to the interplay of complexes containing oxygen vacancies <f>VO</f> and other vacancies, such as <f>VBa</f>, <f>VTi</f> as well as grain boundaries. [Copyright &y& Elsevier]
