| Popis: | The structural investigations of semiconductor gallium phthalocyanine chloride (GaPcCl) in powder form at different temperatures are presented in this paper. Fourier transform infrared spectroscopy, x-ray diffraction and scanning electron microscopy techniques were used to calculate the average crystallite size, D, the dislocation density, δ, micro-strain, the number of crystallites per unit surface area, Nc and average particle size and shape. Indeed, the alternating current (AC) conductivity of the GaPcCl disc was studied as a function of frequency and temperature. The activation energy, the type of conductivity mechanism, the real and imaginary parts of both the dielectric constant and complex electric modulus are determined. |
