Abstract:

This work is devoted to the electrical properties investigation of composite materials AgGe1+xAs1-x(S-FCNT)(3) (x = 0.4; 0.5; 0.6) containing carbon nanotubes in the temperature interval from 10 to 300 K in the frequency range of AC from 1 Hz to 27 MHz. The aim of this paper was to establish temperature ranges corresponding to beginning of appreciable ion transport in AgGe1+xAs1-x(S-FCNT)(3) (x = 0.4; 0.5; 0.6) composite materials, as well as to features identify in the electrical properties behavior in the temperature range from 10 to 300 K. It found that the temperatures corresponding to the beginning of appreciable ion transport in these materials belong to the temperature interval from 170 to 220 K. Moreover, during the study three temperature- and frequency-dependent conductivity regimes were established: (1) NCL regime observed at low temperatures, conductivity is weakly dependent on temperature in this region; (2) Jonscher type region and (3) dc region in which a temperature dependence of the conductivity of the activation type. The presence of three temperature regimes is also observed on the dependencies of the real parts of the impedance versus temperature. (C) 2016 Elsevier B.V. All rights reserved.
