Estimation of Electrical Conductivity and Impedance Spectroscopic of Bulk CdIn2Se4 Chalcogenide

Abstract

The performance of the CdIn2Se4 ac conductivity, dielectric constant and dielectric loss in the pellet shape was studied on varying frequency as well as temperature. The results show that σac(ω) is proportional to ωs by rising frequency. The evaluated estimations of recurrence type diminished from 0.91 to 0.75 by rising the value of temperature. The reliance of AC conductivity on the temperature behavior was explained by the correlated barrier hopping mechanism (CBH). The activation energy values decrease with increasing frequency, affirming that CBH is the fundamental mechanism. Complex impedance curves (Z′ vs Z″) show semicircular arcs due to small relative differences in relaxation frequencies. The attitude of both dielectric constant and dielectric loss as a component of recurrence and temperature was investigated.
