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 ...

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 ...

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 ...

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 ...

A new technical paper titled “Understanding and Optimizing Oxygen Plasma Treatment for Enhanced Cu-Cu Bonding Application” was published by researchers at Seoul National University of Science and ...
