Abstract
This paper examines a method that takes oxidation gradients into consideration when determining optical constants from reflectance and transmission measurements. The oxidation gradients were measured by two techniques using x-ray photoelectron spectroscopy: sputtering, where data are taken at various depths in the sample after removing the surface by sputtering; and variable angle scans, where depth information is obtained by placing the detector at several angles. X-ray photoelectron spectroscopy sputtering was found to give better results for our purposes. This method resulted in very good fits of theoretical data. For more details, see the author’s honors thesis.
