APPLICATIONS
X-ray Photoelectron Spectroscopy (XPS) is a surface-sensitive technique based on the photoelectric effect used to identify a material’s elemental composition and chemical state. Widely used throughout materials science, XPS, also known as photoelectron spectroscopy (PES), requires high vacuum conditions. Developments in near-ambient-pressure XPS (NAP-XPS) have led to investigations of surfaces under more “real-world conditions”, such as in the presence of gases and liquids.
Ion beams are beneficial additions to XPS instruments. It is challenging to keep surfaces perfectly clean, and an ion beam can clean samples before analysis and provide additional depth profiling capabilities. Beams such as C60 are great for many applications, while the emergence of NAP XPS requires a softer beam, for which the GCIB is ideally suited.
