摘要: In this study, frequency and voltage dependence of dielectric constant (e′), loss (e″), tangent (tanδ), the real imaginary parts electric modulus (M′ M″) ac electrical conductivity (σac) an Au/PVA (Bi-doped)/n-Si Schottky barrier diode have been investigated in detail by using experimental C–V G–V measurements wide range 5 kHz–10 MHz ±2 V at room temperature. Experimental results indicate that values e′,e″, tanδ σac are strongly dependent. It has found e′,e″ decrease while σac, M′ M″ increase. is clear show a distinctive peak with U-shape its position shifts towards positive-bias region increasing frequency. Such behavior can be attributed to particular distribution interface states located Si/PVA interfacial polarization. concluded polarization charge easily follow signal low frequencies.
