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 ...

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 ...

Photoelectron spectroscopy of molecular anions is a powerful technique for interrogating the electronic structure and dynamics of negatively charged molecules. By photodetaching an excess electron ...

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.

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 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 ...

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 ...

Faster, more efficient, and more versatile—these are the expectations for the technology that will produce our energy and handle information in the future. But how can these expectations be met? A ...

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 ...

There is much hope for longer-lasting batteries to extend the operational lives of your devices. Researchers from the ...

Physicists have used ultrashort laser pulses to probe the dynamics of photoelectron emission in tungsten crystals. Physicists at Ludwig-Maximilian University in Munich (LMU) and the Max Planck ...
