Abstract
The electrical conductivity and dielectric properties of WO3 nanostructures were measured by impedance spectroscopy using 50 Hz-5 MHz frequency in steps of 100 Hz and 303-383 K temperature. The dielectric behavior is analyzed using real and imaginary parts of dielectric constant (epsilon'), dielectric loss (epsilon ''), loss factor (tan delta), electric modulus (M' and M '') and impedance (Z' and Z '') and complex impedance analysis. The electrical conductivity remained originate towards a function of frequency and temperature. The frequency exponent `s' is found to decrease from 0.89 to 0.35 with an increase of temperature which infers the cor-related barrier hopping mechanism (CBH) that exists in WO3 nanostructures. The Cole-Cole plot explains the complex impedance for different temperatures. (C) 2021 Elsevier B.V. All rights reserved.
