Properties and possibilities of practical applications of GaSe crystal intercalated with β-cyclodextrin doped with iodine

Abstract

The clathrate complex of hierarchical architecture was successfully synthesised by the intercalation of beta-cyclodextrin (β-CD) and molecular iodine (J2) in between the layers of five-fold expanded matrix of gallium selenide (GaSe). The obtained clathrate was investigated by the impedance spectroscopy under normal conditions, at illumination and in the constant magnetic field and the character of clathrate response to the ac electric field was established. As a result of studies of the synthesized GaSe> complex the following phenomena were found: the effect of the effect of negative capacitance, magnetoresistivity effect and magnetodielectric and photodielectric effects. The research result of the obtained clathrate indicates its possible practical application for the creation of nongyrator delay nanolines, the parameters of which can be controlled by a constant magnetic field and the light. The clathrate can also be used as a highly sensitive magnetic field sensor of resistive and capacitive type.
