Temperature and frequency effect on the electrical properties of bulk nickel phthalocyanine octacarboxylic acid (Ni-Pc(COOH)8)

The AC conductivity of nickel phthalocyanine octacarboxylic acid was investigated from 100 Hz to 1 MHz and temperature from 290 to 423 K. The AC conductivity was found to vary with frequency ( σ ( f )) and form two dispersion regions; the associated exponent factor “ s” values were found to vary fro...

Description
Summary:The AC conductivity of nickel phthalocyanine octacarboxylic acid was investigated from 100 Hz to 1 MHz and temperature from 290 to 423 K. The AC conductivity was found to vary with frequency ( σ ( f )) and form two dispersion regions; the associated exponent factor “ s” values were found to vary from 1.17 to 1.34 and from 0.42 to 0.67 (
