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 ...

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 ...

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) ...

As a key precursor in the formation of new particles, sulfuric acid (H 2 SO 4) plays an important role in the formation of aerosols and clouds in the atmosphere. Gas-phase sulfuric acid molecules can ...

Establishing the chemical state and nitrogen concentration is crucial in defining the electronic structure of a material. X-ray photoelectron spectroscopy (XPS) is a technique that is frequently used ...

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 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 ...

The Scienta Omicron HAXPES-Lab provides research-quality, HArd X-ray PhotoElectron Spectroscopy (HAXPES) using an Excillum liquid gallium jet 9.2 keV hard X-ray source and Scienta Omicron EW4000 ...

The X-Ray Photoelectron Spectroscopy Core analyzes the change in surface chemistry of materials after they have been treated with chemicals or physical processes. The XPS Core is centered around a ...
