Abstract
Conducting and transparent indium oxide thin films are prepared by chemical spray deposition of aqueous solution of indium chloride. X–ray diffraction and optical transmission are used to characterize these films. X-ray diffraction study reveals that all the films are highly crystalline and oriented along <222> direction and the film crystallinity increases with increase in film thickness. Band gap energy of the films depends on thickness and varies from 3.53 eV to 3.5 eV. It is observed that resistivity of the films decreases with thickness, while mobility increases.
