“…7 displays Ba 3d 5/2 , O 1s and Ti 2p photoemission spectra of the coatings as well as the reference feedstock powder. The binding energy of Ti 2p 3/2 peak (457.4 eV) is in good agreement with previous XPS studies on BaTiO 3 [27,28]. The O 1s spectra revealed several components.…”

“…7(b) and 8(b) and table 5, both ceramics showed the typical Ba (3d 5/2 /3d 3/2 ) XPS spectrum. The two chemical states at 779.6 eV were assigned to Ba in BaTiO 3 , whereas the higher energy at 794.2 eV was assigned to Ba atom linked with the surface hydroxyl group, as reported earlier [36].

“…For Ba 3d electron energy distance between two peaks is about 15 eV, i.e. approximately the binding energy difference of Ba 2+ to capture an electron [13]. In order to maintain electrical neutrality for precipitation of sodium ions, Nb ion at Ti site provides an electron to the nearest neighbor of the Ba ion.…”

BaTiO 3 ceramics doped with 0.40 mol% NaNbO 3 were prepared using a traditional approach by sintering at temperature of 1250°C to 1290°C. The prepared ceramics was characterized by very good dielectric properties, such as high dielectric constant (1.5 × 10 5 ), low dielectric loss (0.1), and good dielectric temperature stability in the −40°C to 100°C range for the sample sintered below 1270°C. The dielectric characteristics obtained with XPS confirmed that Ti 4+ ions remain in the state without any change. The huge increase in dielectric constant in NaNbO 3 doped BaTiO 3 samples occurs when large amount of Ba 2+ ions are excited to a high energy bound state of Ba 2+ − e or Ba + to create electron hopping conduction. For samples with the content of NaNbO 3 higher than 0.40 mol%, or sintering temperature higher than 1280°C, compensation effect is dominated by cation vacancies with sharply decreasing dielectric constant and increased dielectric loss. The polaron effect is used to explain the relevant mechanism of giant dielectric constant appearing in the ferroelectric phase.
