Electrical, dielectric properties and study of AC electrical conduction mechanism of Li 0.9 □ 0.1 NiV 0.5 P 0.5 O 4 .

In this paper, we report the measurements of impedance spectroscopy for a new olivine-type lithium deficiency Li0.9 □0.1 NiV0.5 P0.5 O4 compound. It was synthesized by the conventional solid-state technique. All the X-ray diffraction peaks of the compound are indexed, and it is found that the sample is well crystallized in orthorhombic olivine structure belonging to the space group Pnma . Conductivity and dielectric analyses of the sample are carried out at different temperatures and frequencies using the complex impedance spectroscopy technique. The electrical conductivity of Li0.9 □0.1 NiV0.5 P0.5 O4 is higher than that of parent compound LiNiV0.5 P0.5 O4 . Temperature dependence of the DC conductivity and modulus was found to obey the Arrhenius law. The obtained values of activation energy are different which confirms that transport in the title compound is not due to a simple hopping mechanism. To determine the conduction mechanism, the AC conductivity and its frequency exponent have been analysed in this work by a theoretical model based on quantum mechanical tunnelling: the non-overlapping small polaron tunnelling model.
