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 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.

The nanoscale world appears to have a new ball to kick around. Researchers from Brown University have shown the first ...

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 ...

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 ...

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 ...

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 ...
