Abstract

This paper reports the fabrication of indium oxide (In2O3) films using a triethylindium and oxygen mixture. The deposition has been carried out on TiAlN substrates (200-350ºC). We have established the correlation between the substrate temperature and the structural properties. The films deposited at 300-350ºC were polycrystalline, whereas those deposited at 200ºC was close to amorphous. XRD analysis and SEM images indicated that the films grown at 350ºC had grained structures with the (222) preferred orientation. The room-temperature photoluminescence spectra of the In2O3 films exhibited a visible light emission.
