X-ray photoelectron spectroscopy, otherwise known as XPS, is a powerful spectroscopic technique for measuring the binding energies of core electrons. X-ray photoelectron spectroscopy as a technique is ...

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 ...

For the first time, and contrary to popular belief, scientists measured the vibrational structure of hydrogen and helium atoms by X-rays. The results disprove the misconception that it’s impossible to ...

AES operates on the principle of the Auger effect, named after the French physicist Pierre Auger. When a material's surface is bombarded with a beam of high-energy electrons or photons, it causes the ...

Spectroscopy methods have been around for a long time now and have been widely used throughout the chemical, biological and engineering fields for many years. Since nanotechnology has developed into ...

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, ...
