Popis: Thick silicon dioxide films were prepared by room temperature oxidation of Si(100) induced by Cu 3 Si. This Cu 3 Si-enhanced oxidation process is accelerated by ultraviolet (UV) light irradiation. Rutherford backscattering (RBS), X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM) were employed to characterize the chemical and structural properties of the silicon dioxide layer underneath the oxidized Cu 3 Si surface layer. The resulting films of silicon dioxide are denser and stoichiometric when silicon oxidation proceeds under UV irradiation at room temperature.
