Tóm tắt

X-ray diffraction (XRD) and Fourier transform infrared (FT-IR) spectroscopy were used to conduct studies of both the crystalline and molecular structure of copper hexadecafluoro-phthalocyanine (F16CuPc). Bulk AC electrical conductivity and dielectric characteristics of F16CuPc were displayed in the pellet form over a temperature range of 293 K to 393 K and a frequency range of 50 Hz to 20 MHz. In this study, the universal power law $$\sigma_{{{\text{ac}}}} \left( {\omega ,T} \right) = A_{ \circ } \omega^{S}$$ has been utilized to explain the frequency exponent response of AC conductivity. The correlated barrier hopping model (CBH) governs the AC conductivity of F16CuPc. The determination of activation energy for the alternating current process was indexed. The barrier height was discovered to be 0.25 eV according to the Giuntini model. The complex impedance $$\left( {Z^{\prime } {\text{vs}} Z^{\prime \prime } } \right)$$ was found to be semicircular. The variation of $$\varepsilon^{\prime } ,\varepsilon^{\prime \prime }$$ as the frequency changes is also investigated. At various temperatures, the bulk of F16CuPc obtained complex permittivity and complex electric modulus.
