“…The presence of this type of depressed semicircle is an indication of the distribution of the relaxation time arising due to dipole-electric field interaction in grain and grain boundary regions. 25 When the applied frequency is low the oscillating electric field can act on the charges comparatively for a longer time before these charges move to the other end of the grain boundary following the direction of the applied electric field. As the thickness of grain boundaries are small compared to that of the grains, this accumulation of charges results a high capacitive effect at low frequency region.…”

BaSnO 3 nanocrystals were synthesized using a simple solid-state route varying the calcination temperature to investigate the effect of grain growth on dielectric properties of this popular perovskite oxide. Duration of calcination was optimized to obtain the pure phase. The samples were characterized by X-ray diffraction, field-emission scanning electron microscopy, transmission electron microscopy and energy dispersive X-ray analysis to investigate crystal structure, morphological information, and elemental composition respectively. The average crystallite size increased from 35 to 49 nm, whereas the porosity decreased from 20.41% to 11.03% with tuning of calcination temperature. The dielectric constant and conductivity increased with calcination temperature whereas the tangent loss maximum was decreased by ∼9%. A non-Debye type relaxation mechanism was confirmed for all samples using Cole-Davidson relations. The outcomes of the electrical properties were correlated with the grain-grain boundary effect, porosity, and brick layer model. It was clearly observed that the effect of high calcination temperature can enhance the room-temperature dielectric constant and conductivity of the nano-BaSnO 3 perovskites.
