Titanium dioxide (TiO2) is known as a material with exceptionally good
optical, mechanical and thermal properties. An increasing interest has
been devoted to the study of TiO2 because of their numerous applications
in various industries. In this study, by controlling process parameters, TiO2
thin films were successfully deposited on a glass substrate using chemical
vapor deposition (CVD) technique. It has been fabricated using two
source materials that are 99.9 % pure titanium and graphite powder at
1000 °C annealing temperature. The deposition time were observed at 1
hour, 2 hours and 3 hours. The TiO2 thin films properties were characterized
using X-Ray Diffraction (XRD), Atomic Force Microscope (AFM), UltravioletVisible
Spectroscopy (UV-Vis), Surface Profilometer (SP) and CurrentVoltage
(I-V) Measurement Tools. Based on XRD results, the intensity of
mixed anatase, rutile, cotunnite type and TiO2 was highest for 3 hours
deposition time. AFM images reveal the crystalline morphology with
average grain size of 151.662 nm. The band gap energy obtained from
UV-Vis as well as thicknesses gained from SP and resistivity acquired from
Current-Voltage (I-V) Measurement of deposited TiO2 thin films were
increasing with deposition time. It is vice versa for the conductivity of
deposited TiO2 thin films that is declining with increasing of deposition time.
It can be concluded from the experimental results that the deposition time
affects the TiO2 thin films properties.
