Abstract :In this study, titanium dioxide insert ignore into journalissuearticles values(TiO2); nanotubes were produced by anodization method using glycerol-based electrolyte. Structural characterization was investigated with SEM images and XRD pattern. The rectifying properties of n-type semiconductor TiO2 nanotubes were investigated. Current-voltage insert ignore into journalissuearticles values(I-V); measurements of the Pt/TiO2 nanotubes/Ti device were made at room temperature, in the dark and under different illumination conditions. The basic diode parameters were calculated by using thermionic emission insert ignore into journalissuearticles values(TE);, Cheung and Norde functions from the I-V measurements of the devices in dark conditions. The ideality factors and barrier height of the Pt/TiO2 nanotubes/Ti device were calculated 1.25 and 0.91 eV, respectively by the TE method. According to the results obtained, the Pt/TiO2 nanotubes contact has a rectifying feature. In addition, the photovoltaic properties of the devices were examined by making I-V measurements at illumination intensities between 30 and 100 mW/cm2. As a result, it has been evaluated that the device can also be used as a photodiode.
