WitrynaInvestigations of impurity centers, electrical resistivity and microstructure of BaTiO 3 ceramics doped with rare-earth ions Y, La, Nd, Sm, Dy and Lu at concentrations x = 0.001–0.005 were carried out. Electron paramagnetic resonance, X-ray diffraction and electron microscopy were used for measurements. The most intense EPR lines were … WitrynaBased on the density functional theory (DFT), we evaluate the effect of sulfur impurity on the stability of cubic zirconia (c-ZrO 2) and its interfaces with metals (Ni, Cu).It is observed that, at low concentration, sulfur atoms have the tendency to locate at the zirconia surface, while at high concentration (∼23.0 wt%), homogeneous ZrOS …
