Abstract
This study was explained the correlation between the O 1s spectra and the crystallization of ITO thin films. The crystal structure of ITO thin films changed with various annealing temperatures and annealing methods such as atmosphere or vaccum conditions. The amorphous structure observed from XRD pattern showed the O 1s spectra with 531.2 eV, and the crystal structure of annealed ITO films analyzed by XRD pattern had the O 1s spectra of 529.8 eV as lower binding energy then the 531.2 eV. Oxygen in view of ITO films was related to the crystallization, and the ITO films annealed in an atmosphere pressure showed higher crystal structure than the ITO annealed in a vaccum. It was indicated that the amorphous structure had higher binding energy than the crystal structure analyzed by O 1s spectra of ITO films.
