Abstract Chalcogenide samples with chemical formula In x Te 20− Se 80 ( = 5, 10 and 15 at %) were prepared using melt quenching method. AC conductivity σ , dielectric constant κ loss tangent tan δ measured two probe method in frequency range from 100 Hz to 5 MHz temperature 26 °C. All exhibited usual dispersion variation of chalcogenides. Conduction activation energy E was determined dependence...
