Sažetak
The ac electrical conductivity and dielectric constant of LiI-AgI-B2O3 glass doped with 0.1 mol. % MnO were investigated in the frequency range from 1 Hz to 1 MHz and the temperature range from 5 K to 450 K. At temperatures below 450 K, an ac conductivity and dielectric constant follow the universal dielectric response (UDR), being typical for hopping or tunneling of localized charge carriers. A detailed analysis of the temperature dependence of the UDR parameter s in terms of the theoretical model for tunneling of small polarons revealed that, below 450 K, this mechanism governs the charge transport in this glass. The comparison of the values of characteristic coefficients W∞ and Eac determined by two different methods confirms the polaronic behavior of this system.
