Nettet1. jan. 2024 · Section snippets XANES simulations. To test the accuracy of the LCF with simulated standards, we use 3 structural models based on the following phases: Cu 2 Te, CuSe, and Cu 2 Se. Cu 2 Te was chosen as it is one of the most prominent Cu-Te phases formed in Cu-doped CdTe (Samoilenko et al., 2024, Zhou et al., 2007) which is our … Nettetcombination of the first two solvent components with relative contributions as free fitting parameters for each delay.

NettetLoaded spectra can be background corrected and all standards can be fitted at once. Two linear combination fitting functions can be used: (1) fit_athena(): Simply fitting combinations of standards as in ATHENA, (2) fit_float(): Fitting all standards with changing baseline correction and edge-step normalization parameters. Nettet4.3 Linear Combination Fitting (LCF): In the present work, LCF has been performed in the XANES spectra (over the range 8960-9040 eV), derivative XANES spectra (over the range 8960-9040 eV) and EXAFS spectra (k2chi and k3chi) (over the range 2-12 Å-1).
