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 become an indispensable tool for elucidating the electronic structure of gas-phase anionic complexes. By irradiating size-selected negative ions with monochromatic ...

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 ...

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.

As the acronym suggests XPS (X-ray photoelectron spectroscopy) is a spectroscopic technique. An XPS spectrum is displayed as the number of photoelectrons collected by the detector as a function of ...

Photoemission spectroscopy (PES) is a powerful analytical technique used to study the electronic structure and chemical composition of materials. It is based on the photoelectric effect, where ...

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 ...

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 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 ...

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 ...
