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 ...

The global pandemic has drastically changed working practices, with many researchers now undertaking ambitious analyses from home and pushing back the frontiers of science from their kitchen table.

Researchers develop a new XPS technique enabling surface studies at atmospheric pressure, enhancing real-world chemical reaction understanding.

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 ...

(a) Experimental schematic and (b) measured unique photoelectron holography from molecular nitrogen. The intercycle interference effect was substantially suppressed when utilizing near-single-cycle ...

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 ...

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 ...

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 ...
