Title: Influence of temperature on the dielectric nonlinearity of BaTiO{sub 3}-based multi-layer ceramic capacitors

Abstract

Temperature dependence of the dielectric nonlinearity was investigated for the BaTiO{sub 3} multilayer ceramic capacitor. The decrease in temperature caused a significant increase in the degree of dielectric nonlinearity. The Preisach analysis shows that such effect corresponds to a decrease in reversible and a significant increase in irreversible domain wall contribution to polarization. The magnitude of spontaneous polarization (P{sub S}) was increased with decreasing temperature. It can be associated with phase transition from pseudo-cubic to monoclinic and its resultant change in the polar direction, which was observed through transmission electron microscopy. These results demonstrate that the increase in P{sub S} with the decrease in temperature inhibits domain wall motion in low driving field as it is anticipated to increase the degree of intergranular constraints during domain wall motion. But it results in a more steep increase in the dielectric constants beyond the threshold field where domain wall motion can occur.

  • It is known (although not well understood) that the dielectric constant of a capacitor in multilayer form (with Ag-based electrode) is somewhat higher than that in disc form. In this work, the authors have systematically studied the effect of Ag addition on the densification and dielectric characteristics of a barium titanate based composition (Z5U type as per Electronic Industry Association (EIA) classification) in disc form. It was found that a small amount of silver addition (in the range of 0.1 wt%) improves the sintered density and dielectric constant values. Possible mechanisms for the observed behavior are delineated.
  • Cu/amorphous BaTiO{sub 3}/Cu capacitors were tested for their dielectric properties in the 0.1 Hz-100 kHz range, from room temperature to 350 degree sign C. The amorphous barium titanate dielectric layer was deposited by rf sputtering on water-cooled copper electrodes. The room-temperature dielectric constant is around 18 and the dissipation factor is 3x10{sup -3} at 100 kHz. When increasing temperature the dielectric response displays an important frequency dispersion with the appearance of a marked loss peak at low frequencies. This dispersion is ascribed to electrode polarization effects, as evidenced by measurements performed on various film thicknesses and by using different electrodes.more » The electrode polarization phenomenon is discussed using a simple space charge model and is shown to be related to mobile oxygen vacancies.« less
  • Properties of pulsed gas lasers pumped by LC inversion circuit made of BaTiO/sub 3/ and SrTiO/sub 3/ series ceramic capacitors were experimentally investigated. The effects of a decrease in capacitance at higher charging voltages on TEA CO/sub 2/ and TE N/sub 2/ laser performances were clarified in terms of discharge voltage, current, power pulse, real stored energy and the energy deposited into the discharge load. Laser performances of the TEA CO/sub 2/ and TE N/sub 2/ lasers with the SrTiO/sub 3/ series capacitor used as an energy storage element of the LC inversion circuit were found to be superior tomore » that of the BaTiO/sub 3/ series capacitor used.« less
  • The doping effect of (Na{sub 0.5}K{sub 0.5})NbO{sub 3} (NKN) as alternatives for rare-earth elements on the electrical properties of BaTiO{sub 3} has been investigated, in terms of their substitution behavior. The dielectric constant of a specimen with x = 0.05 was about 79% higher than that of pure BaTiO{sub 3}, and the temperature coefficient of capacitance was satisfied by the X7R specification. The specimen with x = 0.05 showed the lowest tetragonality among the four compositions and had a fine grain size of <2 μm. Although the addition of NKN decreased the specimen's tetragonality, the electrical properties were enhanced by the formation of defectmore » dipoles and conduction electrons, which resulted from an acceptor and donor substitution behavior. Through O K-edge near edge x-ray absorption fine structure spectroscopy, the practical substitution behavior was defined by the change in Ti 3d orbital states. The energy separation of the Ti 3d orbitals was more apparent with the specimen of x = 0.05, which is related to the donor level from the donor substitution of Nb{sup 5+} ion for Ti-sites. Therefore, the simultaneous substitution of Na{sup +}/K{sup +} and Nb{sup 5+} ions into BaTiO{sub 3} can improve dielectric properties, based on the charge-transfer process.« less
