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...

We investigate the effect of water adsorption on the electrical properties of graphene oxide (GO) films using the direct current (DC) measurement and alternating current (AC) complex impedance spectroscopy. GO suspension synthesized by a modified Hummer's method is deposited on Au interdigitated electrodes. The strong electrical interaction of water molecules with GO films was observed through ...
