SUMMARY
Gold is the preferred reference element for calibrating detectors in X-ray Photoelectron Spectroscopy (XPS) due to its inertness, non-reactive surface, and minimal oxide formation, which allows for accurate calibration of the Fermi level. While other metals like platinum (Pt) can also serve as reference elements, they may not provide the same level of reliability under charge effects. The discussion highlights that with proper grounding, any metal can theoretically be used, but gold remains the standard due to its unique properties.
