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 emerged as a cornerstone technique for probing the electronic structure of organic molecules, offering direct measurement of binding energies and orbital character ...

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 ...

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.

For the first time, researchers have been able to measure the quantum state of electrons ejected from atoms that have absorbed high-energy light pulses. This is thanks to a new measurement technique ...

The world's first dual-beamline photoelectron momentum microscope has been developed at the UVSOR Synchrotron Facility, Japan. This innovative experimental station brings breakthroughs in studying 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 ...

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 ...

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.

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 ...
