| dc.description.abstract | This thesis discusses transparent conductive oxides (TCOs), which are materials with unique physical properties as they combine high electrical conductivity with optical transparency. Tin dioxide (SnO₂) is highlighted as an n-type semiconductor that has high electrical conductivity, visible light transparency, and a wide band gap ranging from 3.5 to 3.8 eV. These properties make it suitable for applications like gas sensors, transparent electrodes, and photocatalysis. To further improve its physical properties, doping with zinc and copper is carried out. The work also focuses on the deposition of SnO₂ thin films using spray pyrolysis, a technique chosen for its simplicity, low cost, and ability to produce uniform films in an oxygen-rich environment. The thesis is structured into three chapters: the first chapter presents a bibliographic study of TCOs and thin films, analyzing SnO₂ properties and its applications while introducing photocatalysis and the reasons for using SnO₂ in this study. The second chapter explains the experimental methods, including spray pyrolysis with the Holmarc device, steps for preparing thin films, and discusses doping and semiconductors. The third chapter presents a comparative study of the structural, optical, and electrical properties of pure and Cu, Zn-doped SnO₂ thin films . | |
