“…Due to the nanofibrous (nanochain) structure of crystals of this family, the disorder of Tl + sublattice occurs, while, nanodimensial chains of In +3 Se2 -2 -TlInSe2, In +3 Тe2 -2 -TlInTe2, Tl +3 Se2 -2 -TlSe and Tl +3 S2 -2 -TlS make up topologically disordered mesoscopic structures ( Figure 5). Such mesoscopic systems possess a number of unique properties, which are not observed in usual 3D structures, namely: giant dielectric permeability [25], giant magnetic reluctances, Fogel-Fulcher's law implementation, giant dielectric relaxation, terahertz libration oscillations and other peculiarities. The peculiarities of the crystals of the TlGaTe2 family in superion phase, namely, existence of nanofibrous topologically disordered structure, allows to construct electrolytic accumulators with parameters exceed in quality than known samples [26].…”

In this paper we present the most recent results of our studies on TlInTe2 and TlInSe2 crystals (continuing our earlier studies on TaGaTe2), and analyze the nano-size application perspectives of A 3 B 3 C 6 2 semiconductors. It has been shown that A 3 B 3 C 6 2 semiconductors are prospective materials for developing the nano-size devices such as varistors, solid electrolytic accumulators and supercapacitors. The analysis is based on our experimental studies, which include the temperature dependence of the electrical conductivity, THz spectra, and permittivity. It has been shown that the electrical conductivity parameters of A 3 B 3 C 6 2 type semiconductors can be affected by-irradiation, and the effect depends on the dose of irradiation. The possibility of restructuring of electrical conductivity mechanism in these semiconductors makes them attractive for designing new nano-size electronic devices with controlled parameters.

“…It is suggested that the switching effect is related to the transition of crystals to the superionic state, which is accompanied by diffusion of Tl + ions. This conduction mechanism is typical of superionic conductors [6][7][8][9]. The transition to the high-conductivity state in superionic conductors occurs generally as a result of the first order phase transition and is explained by the stepwise disordering of one of the crystal sub-lattices (generally cationic) with the other sub-lattice either remaining invariable or transforming but retaining the crystal hardness.…”

-In this paper, we report the results of our studies on temperature and electric field dependences of conductivity in TlS, TlSe and TlInS2 crystals. At a certain temperature (typical for all three crystals) a switching effect has been observed for the conductivities of all crystals. The switching effect is explained by the phase transition to the superionic conductivity. It is suggested that in TlS and TlSe crystals the ion conductivity is caused by the diffusion of Tl + ions over vacancies in the thallium sub-lattice between (Tl 2) chains. In TlInS2 crystals, this effect is due the diffusion of Tl + ions towards vacancies in the Tl sub-lattice. In all crystals Stype switching effect is revealed. It is suggested that the switching effect is related to the transition of crystals to the superionic state, which is accompanied by diffusion of Tl + ions.
