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 ...

DeepCore-X is engineered to meet the demands of researchers working on semiconductors, energy materials, advanced coatings, and interface devices. Its key features include: Synchrotron-like ...

The initial oxidation behavior of metallic copper, tin, and three single-phase Cu-Sn alloys (an $\alpha$ phase solid solution alloy, and the intermetallic compounds ...

X-ray spectroscopy measurements that previously needed to be done at a synchrotron facility could become available to a broader audience thanks to a new tabletop system (Anal. Chem. 2022, DOI: 10.1021 ...

To understand how materials work, whether a metal in a car’s catalytic converter or the substances in a battery, scientists need to look at their surfaces at the atomic level. One of the best tools ...

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 ...

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 ...

X-rays, a type of electromagnetic radiation with wavelengths from 0.01 to 10 nanometers, pack enough energy to pierce materials and interact with inner-shell electrons. 1 When they hit a sample, ...
