EN

The dielectric properties of cobalt phthalocyanine are investigated in the frequency range 50-5×10^{5} Hz and within the temperature range 293-363 K. The frequency dependence of the AC impedance could be expressed by the complex plane of the complex impedance. Analysis of the AC conductivity reveals semiconducting features based predominantly on the hopping mechanism. The relaxation time, derived from the experimental results, shows a thermally activated process.
