Abstract

The results of studying the characteristics of an expanded InSe matrix with propolis intercalated between its layers are presented. The nature of changes in the frequency behavior of the impedance under normal conditions, in a constant magnetic field and under illumination is determined. It was found that the introduction of propolis between the layers of InSe single crystal leads to a 4-fold decrease in the real part of the impedance. A positive magnetoresistance and an anomalous positive photoresistive effect were recorded for the InSe<propolis> intercalate. The intercalate InSe<propolis> is characterized by a quasi-continuous impurity spectrum as evidenced by the recorded currents of the thermally stimulated discharge. Using the theory of hopping conductivity proposed by M. Pollack and T.H. Geballe, which takes into account the hopping of charge carriers between states localized in space due to their interaction with phonons, the density of states at the Fermi level, the density of deep traps, the scattering of trap levels near the Fermi level and the average hopping distance were calculated.
