Electrical impedance investigation of gamma-irradiated TlInS2〈5%C〉 crystals

Abstract

In this article, the authors carry out a pioneering study of monocrystalline TlInS[Formula: see text] at higher than room-temperatures using impedance spectroscopy. It is shown that in TlInS[Formula: see text] crystals at temperatures higher than 400 K, the nature of conductivity is predominantly ionic. Moreover, characteristics of impedance spectra behavior of TlInS[Formula: see text] monocrystal samples were studied using the measurement frequency range of 25–106 Hz. For the measured frequency range, it is shown that curves of active and reactive impedance components undergo a dispersion characterized by decreasing values of [Formula: see text] and [Formula: see text], as the frequency of the electric field and radiation dose increases.
