Abstract

In this study, voltage and frequency dependent dielectric properties of Au/n-CdTe Schottky diodes grown by thermal evaporation method were investigated. The frequency and voltage dependent of capacitance-voltage (C-V) and conductance-voltage (G/ω-V) characteristics were measured in the frequency range of 1 kHz - 500 kHz at room temperature. Dielectric constant (ε^'), dielectric loss (ε^''), dielectric loss tangent (tan⁡δ), the ac electrical conductivity (σ_ac), and complex impedance (Z^*) were calculated from the C-V and G /ω -V characteristics and plotted as a function of frequency.
