    Raman investigation of the ageing of Ni-BaTiO3 multilayer ceramic capacitors
    (Springer Link, 2008-02) Umeri, Andrea; Scuor, Nicola; Kuku, Adelaja Titilayo; Sergo, Valter
    Ni-BaTiO3 multilayer ceramic capacitors (MLCC) have been aged at 121°C and 100% Relative Humidity for 2,600h. Raman and energy dispersive spectral measurements have been made on both aged and unaged samples. Raman spectra indicate the presence of a coating of substoichiometric SnO x (1
