abstract = "BaTiO3 (BTO) is considered the most commonly used ceramic material in multilayer
ceramic capacitors due to its desirable dielectric properties. Considering that the miniaturization of electronic devices represents an expanding field of research, modification
of BTO has been performed to increase dielectric constant and DC bias characteristic/sensitivity. This research presents the effect of N2 and air atmospheres on morphological and dielectric properties of BTO nanoparticles modified with organometallic salt
at sintering temperatures of 1200◦C, 1250◦C, 1300◦C, and 1350◦C. Measured dielectric
constants were up to 35,000, with achieved very high values in both atmospheres. Field
emission scanning electron microscopy (FESEM) was used for morphological characterization, revealing a porous structure in all the samples. The software image analysis
of FESEM images showed a connection between particle and pore size distribution, as
well as porosity. Based on the data from the image analysis, the prediction of dielectric
properties in relation to morphology indicated that yttrium-based organometallic salt
reduced oxygen vacancy generation in N2 atmosphere. DC bias sensitivity measurements
showed that samples with higher dielectric constant had more pronounced sensitivity to
voltage change, but most of the samples were stable up to 100 V, making our modified
BTO a promising candidate for capacitors.",
