HIERARCHICAL HETEROSTRUCTURE SYNTHESIZED ON THE BASIS OF AN INDIUM SELENIDE SEMICONDUCTOR MATRIX AND SUPRAMOLECULAR COMPLEX THIOUREA<COBALT(II) CHLORIDE>: FABRICATION AND PHYSICAL PROPERTIES

Abstract

The InSe<CH₄N₂S<CoCl₂>> clathrate was formed using intercalation technology with a hierarchical arrangement of components according to the principle of subhost<host<guest>>. Conductive and polarizing properties of the obtained clathrate in the frequency range of 10^-3 – 10⁶ Hz were investigated using impedance spectroscopy. Measurements were carried out under normal conditions, with the application of a permanent magnetic field with a strength of 220 kA/m and under illumination (illumination was carried out by a solar spectrum simulator with a power of 982 W/m2). The structure of the impurity energy spectrum near the Fermi level was investigated using the thermostimulated discharge method in the temperature range from 240 to 340 K. In the InSe<CH₄N₂S<CoCl₂>> clathrate, the manifestation of the memristor effect, the positive magnetocapacitive effect and the photoelectric effect of 25 mV were recorded.
