Abstract

We used the solid state method to synthesize the α-KZnPO4 compound.

An investigation of structural, thermal, and electrical conductivity properties for understanding transport mechanisms of CuWO4 and α-CuMoO4 compounds

“…Indeed, it is important to note that the non-ideal Debye behavior and the observed depression of the semicircles are both explained by the presence of a constant phase element (CPE) in these equivalent circuit models. 23 …”

“…22 Indeed, it is important to note that the non-ideal Debye behavior and the observed depression of the semicircles are both explained by the presence of a constant phase element (CPE) in these equivalent circuit models. 23 The impedance of the CPE contribution is an empirical function of the following type: where Q is the capacitance value of the CPE element; u is the angular frequency; and a is a parameter indicating the change of the compressed semicircle from an ideal semicircle. The frequency behavior of the complex impedance parts (−Z ′ ′ ) of the a-CuMoO 4 and CuWO 4 samples, for distinct temperatures, is displayed in Fig.…”

Investigation of Morphology, Optical and Electronic Ac Conduction of the Olivine Manganite Compound: NaMnPO4

“…According to the literature review, the frequency conductivity dependence for the orthophosphate group is characterized by a relatively low-frequency-dependent plateau at a lower frequency area related to the DC conductivity and frequency dispersion at the high-frequency region attributed to AC conductivity. [59][60][61] Figure 12 displays the variation in conductivity with frequency and temperature for the NaMnPO 4 material. The electrical conductivity spectra can be evaluated, corresponding to two types of behavior in the analyzed frequency range.…”
