ZnO:TiO2 NANOKOMPOZİT İNCE FİLMLERİN ELEKTRİKSEL ÖZELLİKLERİ

Abstract

In this work, ZnO:TiO2 nanocomposites thin films were produced, and electrical properties were evaluated. Nanocomposite nanoparticles were used as thin film source in the preparation which was produced using sol-gel synthesis in different concentrations. Spin coating process was adopted in the preparation of ZnO:TiO2 nanocomposites films. In the thin film preparation pure TiO2, and nanocomposites in 1:5 ZnO:TiO2 and 1:2 ZnO:TiO2 concentrations were prepared. Electrical properties of the ZnO:TiO2 composites were assessed where capacitance-voltage and conductancevoltage measurements were performed. Adjusted conductance (Gadj)-voltage (V) and adjusted capacitance (Cadj)-voltage (V) characteristics were studied. Frequency dependent characteristics were obtained in the electrical measurements. The density of interface states (Dit) was assessed; results illustrated that the Dit has frequency dependent characteristics.
