Iron(III) tert-butoxide was applied as a single source (both Fe and O) precursor for the deposition of nanocrystalline hematite (Fe2O3) or magnetite (Fe3O4) films by low-pressure CVD. Fe3O4 and Fe2O3 layers deposited on glass substrates were transparent to the visible light, as was determined from the absorption spectra. Nanocrystalline Fe3O4 and Fe2O3 films demonstrated sheet resistance 2.4 kΩ and 2 MΩ, respectively. See link below
