Preparation and Characterization of Iron(III) Oxide Films by an Novel Spray Pyrolysis Method.

摘要

Alpha-Fe203 thin films were deposited on silicon substrates by nebulization of a 0.01 M solution of iron acetylacetonate in a 50% methanol/water mixture followed by pyrolysis and annealing in flowing oxygen. The resulting films were characterized by x-ray diffraction, scanning electron microscopy, and their electrical transport behavior. The IR transmission spectrum of alpha-Fe203 recorded from such films agreed with published theoretical analysis based on the crystal structure.
