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 ...

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 ...

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 ...

This is the basic principle of photoelectron spectroscopy. The electron that is emitted, known as the photoelectron, is often treated as a classical particle. In reality, the photoelectron is a ...

The basic physical process of irradiating a material with photons of a known energy and measuring the ejected photoelectrons has remained unchanged over six decades since it was first commercialized.

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 ...

Faster, more efficient, and more versatile—these are the expectations for the technology that will produce our energy and handle information in the future. But how can these expectations be met? A ...

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.
