Abstract
Comprehensive study of the electrochemical, electrical properties and temperature dependences of the Zn (II) hybrid organic complex based on Schiff (C48H42N6O2Zn) is carried out. In order to determine the prospects for using this compound as a semiconductor material, thin films were obtained using the centrifugation method. The method of preparation, synthesis, microscopy of the surface, as well as the method of measuring the temperature dependences of the electrical properties of the obtained thin films are described. The temperature measurement range ranged from 270 to 330 K. The energy levels of the lowest unoccupied molecular orbital and the highest occupied molecular orbital were determined using cyclic voltammetry. The activation energy calculated from linear approximations of the current-voltage characteristics in Arrhenius coordinates was 0.65 eV. Analysis of the current-voltage characteristics of the ITO – PBAL – Al structure showed that they correspond to the typical characteristics of Schottky diodes with a charge mobility of ~ 1,18·10–11 cm2·V–1·s–1.To study the mechanisms of charge transfer, the C – V characteristics of the samples were investigated at a frequency of 1 kHz. The concentration of charge carriers was calculated using the Mott – Schottky relationship.
