Impedance spectroscopy study of Pb2P2O7 compound

Abstract

The lead pyrophosphate, Pb 2 P 2 O 7 , compound was prepared by conventional solid-state reaction and identified by X-ray powder diffractometer. Pb 2 P 2 O 7 has a triclinic structure whose electrical properties were studied using impedance spectroscopy technique. Both impedance and modulus analysis exhibit the grain and grain boundary contribution to the electrical response of the sample. The temperature dependence of the bulk and grain boundary conductivity were found to obey the Arrhenius law with activation energies E g =0.66 eV and E gb =0.67 eV, respectively. The scaling behavior of the imaginary part of the complex impedance suggests that the relaxation describes the same mechanism at various temperatures.

Impedance Spectroscopy Study of Bis(2-Amino-6-Methylpyridinium) Tetrachloridozincate

“…19 Figure 6(b) shows that Argand diagram (imaginary part of complex impedance Z Ã versus its real part) allows the determination of bulk ohmic resistance as a function of temperature and thus temperature dependence of conductivity. 20 The good conformity of the calculated lines with experimental data observed in Fig. 6(a) indicates that the suggested equivalent circuit describes the crystalÀelectrolyte interface reasonably well.…”

Structural and electrical properties of Cu2Zn(Sn1−xSix)S4 (x=0, x=0.5) materials for photovoltaic applications

“…AC conductivity of compound A05 shows two plateaus separated by a frequency dispersive region are observed in the pattern. The low-frequency plateau represents the total conductivity whereas the high frequency plateau represents the contribution of grains to the total conductivity [35]. The presence of both high and low frequencies plateaus in conductivity spectra indicates the presence of two processes contribute to the conduction.…”
