Our deconvolution strategy provides a simple guideline for obtaining high-quality fits to experimental data on the basis of a careful evaluation of experimental conditions and results. The deconvolution method proposed provides C/(N + O) ratios in very good agreement (error less than 5%) with those obtained from total C 1s, N 1s and O 1s peaks. These reference pages contain tips and techniques that are designed to help both the novice and advanced XPS user. More details at the companys official site. With the DFT calculations, spectral components arising from surface-defect carbons could be distinguished from aromatic sp 2 carbon. X-ray photoelectron spectroscopy (XPS or ESCA) curve fitting procedures, reference materials and useful notes are listed here to provide a starting point for the consistent interpretation of XPS spectra. Nanolab offers useful resources - software and PDF books and loose-leaf books of monochromatic XPS spectra. Furthermore, we propose an expanded method to improve the self-consistency of the XPS interpretation based on a seven-peak C 1s deconvolution (3 C–C peaks, 3 C–N/-O peaks, and π-π∗ transition peaks). To improve the interpretation of XPS spectra of nitrogen-doped carbons, the C 1s, N 1s and O 1s core level energy shifts have been calculated for various nitrogenated carbon structures via DFT. The plot is constructed for each species by taking the logarithm of the ratio of the XPS peak area at near grazing emission angle to that at near normal emission. Relative Depth Plot This is the simplest treatment for ARXPS data and shows the ordering of layers within an ultra-thin lm. Quantifying the content of surface nitrogen and oxygen containing functional groups in amorphous nitrogen doped carbons via deconvolution of C 1s x-ray photoelectron (XPS) spectra remains difficult due to limited information in the literature. of the software is based, refer to application note 31014.
