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 ...
For the first time, researchers have been able to measure the quantum state of electrons ejected from atoms that have absorbed high-energy light pulses. This is thanks to a new measurement technique ...
The study of the electronic structure of anionic clusters using photoelectron spectroscopy (PES) has provided profound insights into the quantum mechanical nature of these complex systems. By ...
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 ...
Performing X-ray photoelectron spectroscopy with ungrounded samples requires additional considerations to avoid spectra ...
High-Pressure Photoelectron Spectroscopy (HPPES) advances catalysis research by enabling real-time surface analysis under ambient and high-pressure conditions.
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 ...
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 ...
