Calibration of Binding Energy Positions with C1s for XPS Results
TL;DR: In this article, the adventitious carbon located at 284.8 eV was used to calibrate samples without the carbon themselves and compared with gold and argon, a more practical and convenient method based on C1s was proposed to get the right positions for binding energy peaks.
