Comparison of parameter choice methods for the analytical inversion of ARXPS data
D Peykov, RW Paynter - Journal of Electron Spectroscopy and Related …, 2014 - Elsevier
Using 0th order Tikhonov regularization, we recovered concentration-depth profiles from
simulated noisy ARXPS data using nine candidate methods for the selection of the
regularization parameter α. Calculations were performed on 1000 noisy data sets at 10
levels of noise ranging from 0.1% to 9%. By comparison with the input profile, the parameter
choice methods were rated in terms of the accuracy and reproducibility of the extracted
profiles. We discuss the results obtained in the context of the inputs and constraints required …
