The positron lifetime spectra in 0.25 at.% La-doped BaTiO, with different Ba/Ti ratios have been measured at room temperature. It was found from the experiments that with deviating from exact stoichiometry the positron lifetime z2 decreases and the intensity I , increases for Ba/Ti ratio smaller tha
We have studied polycrystalline BaTiO 3 by using cathodoluminescence (CL), scanning tunneling and electron microscopy (STM and SEM) and Auger electron spectroscopy. The main aim of the work was the characterization of the grain boundaries of the polycrystalline material by STM which show up in the C
