Dielectric characteristics such as dielectric constant (ε′), dielectric loss (ε″), dielectric loss tangent (tanδ) and real and imaginary parts of electrical modulus ( Μ ′ and Μ ″), and ac electrical conductivity ( σ ac ) of Au/ Polyvinyl Alcohol ( PVA ) (Bi 2 O 3 ‐dispersed)/n‐Si structures have been investigated by using admittance measurements. Results show that the ε′ values of Au/ PVA /n‐Si with Bi 2 O 3 ‐dispersed PVA interfacial layer are very higher compared with those with pure and other dopant/mixture's of PVA . Thus, PVA is made very compatible for device applications with the enhanced dielectric properties by Bi 2 O 3 disperse and its native very high dielectric strength.
