Effect of masses of active layers of C60-4-methylphenylhydrazone N-isoamylisatin fullerene heterostructures on their rectifying characteristics

Abstract

An organocarbon heterostructure consisting of thin films of fullerene and 4-methylphenylhydrazone N-isoamylisatin was obtained from a solution by irrigation. The procedure for obtaining the samples, the microscopy, and synthesis of the initial powder material have been described. The results of an alternate X-ray phase analysis of the substances used has been presented. The analysis of changes in the electrical and optical characteristics of the active layers, depending on the mass of the solid phase has been carried out. The relationship between a sequential increase in film thickness and an increase in the absorption coefficient of infrared electromagnetic radiation has been revealed. Having determined the optimal thicknesses of the active layers of the heterostructure, based on fullerene C60 and 4-methylphenylhydrazone N-isoamylisatin, we achieved an increase in photoconductivity by two orders of magnitude. The obtained light current – voltage characteristics of such thin-film structures are rectilinear in nature with a direct load of up to 10 V.
