Impedance spectroscopy study of Cu6PS5I–As2S3 nanocomposites

Nanocrystalline Cu6PS5I powder has been mixed with As2S3 semiconducting glass to obtain nanocomposite. Surface of the obtained sample has been photographed by scanning electron microscope. Electrical properties of Cu6PS5I–As2S3 nanocomposite have been measured using two- and four-probe methods. The obtained results were analyzed by fitting the experimental data to the equivalent circuit model. Warburg impedance element described Cu6PS5I nanoparticles, and the phase transition of this material was indicated.
