Abstract
Titaniumdioxide (TiO2) Thin Films Have been Fabricated and Deposited on Ftoglass Substrates by Spray Pyrolysis Deposition (SPD) Method. the TiO2thin Films were Annealed at Four Different Temperatures for an Hour. Thetemperature was Set at 100°C, 300°C, 400°C and 500°C. Surface Morphology Andelectrical Properties of TiO2 Thin Films were Investigated Usingfesem and 2 Point- Probe I-V Measurement, Respectively. the FESEM Result Shows Thatthe Grain Size of the Tio2 increases when Annealed Temperatureincreases. for XRD Test Shows that the Crystallinity Improved with Theincreasing of Annealing Temperature. when the Annealing Temperature Increases,the Electrical Properties of TiO2 Also Change. the Result Shows Thatthe Optimum Temperature for Annealing of TiO2 Thin Film was 400°C.
Highlights
Titanium dioxide is known as a crucial material as it is extensively used as pigment in paints and coating materials in optical thin films
This study focuses on the effect of annealing temperatures on TiO2 thin films prepared by spray pyrolysis deposition (SPD) method in terms of structure, surface morphology and electrical properties
Titanium dioxide thin films are successfully fabricated onto FTO glass substrates using spray pyrolysis deposition (SPD) method which annealed at four different temperatures
Summary
Titanium dioxide is known as a crucial material as it is extensively used as pigment in paints and coating materials in optical thin films This is due to its high transparency and high refractive index and its chemical durability in the visible and near IR region [1]. TiO2 thin film can be fabricated using many different techniques such as sol-gel, DC magnetron sputtering, chemical vapor deposition, spin-coating and spray pyrolysis deposition (SPD) method [3]. This study focuses on the effect of annealing temperatures on TiO2 thin films prepared by spray pyrolysis deposition (SPD) method in terms of structure, surface morphology and electrical properties. The TiO2 thin film was fabricated onto the substrates by using spray pyrolysis deposition (SPD) method on a hotplate set at 150°C. The samples of the TiO2 thin films were characterized by using Field Emission Scanning Electron Microscope (FESEM), XRD and 2 point- probe I-V measurement
