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 ...

XPS relies on the photoelectric effect, where irradiating a material with X-rays causes the emission of core electrons. The kinetic energy of these emitted electrons is measured, which can be directly ...

An ultraviolet photon-counting dual-comb spectrometer. Two ultraviolet frequency combs of slightly different pulse repetition frequencies are generated at very low light levels by nonlinear frequency ...

Physicists achieve major leap in precision and accuracy at extremely low light levels. Researchers at the Max Planck Institute of Quantum Optics (MPQ) have successfully developed a new technique for ...

Beamlines BL6U, BL7U, the newly constructed BL7U branch, and electron storage ring are highlighted in dotted lines. The upper (lower) left insetshows the photoelectron momentum pattern of the Au(111) ...

High-Pressure Photoelectron Spectroscopy (HPPES) advances catalysis research by enabling real-time surface analysis under ambient and high-pressure conditions.

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 ...

Researchers at the Max Planck Institute of Quantum Optics (MPQ) have successfully developed a new technique for deciphering the properties of light and matter that can simultaneously detect and ...

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 ...
