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 ...

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 ...

Performing X-ray photoelectron spectroscopy with ungrounded samples requires additional considerations to avoid spectra ...

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 ...

New research shows that X-ray photoelectron spectroscopy (XPS) can give misleading analysis results due to an erroneous assumption during calibration. X-ray photoelectron spectroscopy (XPS) is often ...

X-rays, a type of electromagnetic radiation with wavelengths from 0.01 to 10 nanometers, pack enough energy to pierce materials and interact with inner-shell electrons. 1 When they hit a sample, ...
