FOURIER-TRANSFORM INFRARED SPECTROSCOPIC STUDY OF OXIDE-FILMS GROWN IN PURE N2O

Abstract

The properties of the oxide films grown by pure N2O were studied in this work. A two-layer model, considering a N2O oxide with an oxy-nitride film at the interface, was used to describe the dependence of the main peak shift in a Fourier transform infrared (FTIR) spectrum on N2O thicknesses. The thickness of interfacial layer was determined by FTIR and multiple-angle incident ellipsometer. Both methods showed consistent results and the thickness of this layer is found to be 14-16 Angstrom.
