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 ...

Researchers synthesized urchin-like microspheres containing both CuO and Cu2O phases and traced a copper-rich core giving way ...

Photoelectron spectroscopy (PES) has become an indispensable tool for elucidating the electronic structure of gas-phase anionic complexes. By irradiating size-selected negative ions with monochromatic ...

The surface chemistry of catalyst nanoparticles is crucial for understanding catalytic mechanisms of reactions significant for chemical transformation, energy conversion and environmental ...

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.

A laboratory study on one graphite anode found that simulated charge neutralization during XPS shifted fluorine-, phosphorus- ...

A new momentum microscopy experimental station for photoelectron spectroscopy resolved in 3D momentum space with a microscopic field of view has been built at BL6U of UVSOR *, Institute for Molecular ...

Researchers have observed a molecule in the first instants after it has absorbed light and tracked the coordinated motion of ...

For the first time scientists measured the vibrational structure of hydrogen and helium atoms by X-rays. The results disprove the misconception that it's impossible to obtain X-ray photoelectron ...

X-ray photoelectron spectroscopy (XPS) is often used to determine the chemical composition of materials. It was developed in the 1960s and is accepted as a standard method in materials science.

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 ...
