X-ray photoelectron spectroscopy is based on the same principle as all photoelectron spectroscopy methods. If a molecule or material is irradiated with light of a known energy above the ionization ...

Photoelectron spectroscopy (PES) is a surface-sensitive analytical technique that provides information about the elemental composition, chemical state, and electronic structure of a material's surface ...

Discover why surface chemistry matters and how XPS imaging modes enable deeper insight into materials performance.

The solid electrolyte interphase (SEI) plays a pivotal role in governing the performance and stability of lithium (Li) batteries. X-ray photoelectron spectroscopy (XPS) is a powerful technique for ...

A recent article in Advanced Materials Interfaces presented a method to more accurately determine the surface chemistry of Ti 3 C 2 T x MXenes. The authors used energy-dependent X-ray photoelectron ...

Researchers develop a new XPS technique enabling surface studies at atmospheric pressure, enhancing real-world chemical ...

Graphene is a single-atom-thick carbon sheet discovered in 2004. The crucial question during graphene synthesis is, "How do I know that the material I'm making is actually single-atom thick?" Because ...
