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 ...

Anion dynamics and photoelectron spectroscopy collectively offer a powerful means to elucidate the transient behaviour of negatively charged species in chemical reactions. This field explores how ...

The basic physical process of irradiating a material with photons of a known energy and measuring the ejected photoelectrons has remained unchanged over six decades since it was first commercialized.

Thermo Fisher launches Hypulse, a new XPS system with femtosecond laser tech for faster, deeper surface analysis.

A research team from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has constructed a copper (Cu ...

Auger electron spectroscopy is a well-established surface-sensitive technique. It has been mostly used for the identification of species on sample surfaces, especially to monitor the process of sample ...

An X-ray photoelectron spectrometer is an impressive bit of kit. The relatively low energy of the detected photoelectrons dictates that the experiments are performed in ultra-high vacuum. The ...

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 ...
