Investigation on electrical transport and dielectric relaxation mechanism in TbCrO3 perovskite orthochromite

Non-classical electrostriction in calcium-doped cerium oxide ceramics

“…64 Ultimately, 3 0 reached a steady value in the highfrequency region, i.e., the dielectric constant value of the material. 65 The 3 0 (T) at low frequencies varies signicantly between the samples. At higher frequencies, ∼100 kHz, the change in 3 0 is considerably less temperature-dependent, having a comparable value for all samples, suggesting a similar dipolar activity.…”

Crystal Structure and Spectroscopic Characterization of a New Hybrid Compound, (C12H17N2)2[CdBr4], for Energy Storage Applications

“…The Zview program was employed to match the observed impedance measurement with a standard equivalent circuit consisting of two parallel elements, R–C (grain effect) and R–Q (grain boundary effect), arranged in series, as depicted in the inset of Figure . The Constant Phase Element (CPE) is utilized in the equivalent circuit to compensate for nonideal capacitance behavior that might occur due to the presence of numerous relaxation phenomena in the (C 12 H 17 N 2 ) 2 [CdBr 4 ] system with nearly equal or comparable relaxation periods. , The formula for CPE’s capacitance is Z CPE = 1 Q false( j ω ) α …”
