Corrosion-, chemical-resistant pure iron thin films were formed by the vacuum ultraviolet fluorine laser of 157 nm wavelength induced surface modification of 30- to 50-nm-thick iron thin films. Transmission electron microscope and electron energy-loss spectroscopy were conducted to analyze structure and oxidation state of the thin modified layer of iron thin films. No rust was observed on the surface of the fluorine laser-irradiated iron thin films in air for 2 years. The samples also showed high chemical resistance to a HNO aqueous solution to fabricate a micropattern of pure iron thin films. [ABSTRACT FROM AUTHOR]
