Dielectric Relaxation and Non‐Overlapping Small Polaron Tunneling Model Conduction Studies of Ag_2‐xNa_xZnP₂O₇ (x = 0, 1, and 2) Materials

The Ag 2− x Na x ZnP 2 O 7 ( x = 0, 1, and 2) materials are prepared using the solid–solid method followed by heat treatment. The investigated samples are characterized by combining X‐ray powder diffraction and electrical impedance spectroscopy techniques. The Rietveld refinement of the X‐ray diffraction (XRD) pattern revealed that these Ag 2 ZnP 2 O 7 , AgNaZnP 2 O 7 , and Na 2 ZnP 2 O 7 compounds are indexed in the tetragonal system with the...
