Electrophysical properties of supramolecular ensembles InSe, InSe AND InSe>

Abstract

The dependence of electric conductivity properties of supramolecular ensembles InSe<CH4N2S>, InSe<FeSO4> and InSe<CH4N2S<FeSO4>> on the hierarchization degree of guest component was established in the work. It was shown in particularly, the insertion of thiourea into interlayer space of single crystal InSe results in 3 folded decrease in real component of specific complex impedance of intercalate in the work. As it was approved by calculation, the thiourea insertion leads to drastic changes in density of states at Fermi level, jump length and trap centers dispersion. Experimental results of thermodepolarizing current investigation confirmed calculations as well. At the same time Iron (II) Sulfate insertion leads to the negative capacitance effect at lighting, what opens a new view on photoregulated delay lines technologies. But the cointercalation of thiourea and Iron II Sulfate does not lead to above listed effects. Magneto- and photo- sensitivity of obtained intercalates was investigated.
