Ukrainian Journal of Physics| Zusammenfassung: | Impedance measurements of (Cu1−xAgx)7GeS5I mixed crystals are carried out in the frequency range from 10 Hz to 300 kHz and in the temperature interval 292–383 K. The temperature and frequency dependences of the electrical conductivity for (Cu1−xAgx)7GeS5I mixed crystals are studied. Based on the analysis of Nyquist plots and using the electrode equivalent circuits, the values of ionic and electronic components of the electrical conductivity are determined. The compositional behavior of the ionic and electronic conductivities, as well as the compositional behavior of their activation energies, are discussed. The ratio of ionic and electronic components of the conductivity for (Cu1−xAgx)7GeS5I mixed crystals was analyzed. |
