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 ...
Performing X-ray photoelectron spectroscopy with ungrounded samples requires additional considerations to avoid spectra ...
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 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.
A recent article in Advanced Materials Interfaces presented a method to more accurately determine the surface chemistry of Ti 3 C 2 T x MXenes. The authors used energy-dependent X-ray photoelectron ...
The solid electrolyte interphase (SEI) plays a pivotal role in governing the performance and stability of lithium (Li) batteries. X-ray photoelectron spectroscopy (XPS) is a powerful technique for ...
High-Pressure Photoelectron Spectroscopy (HPPES) advances catalysis research by enabling real-time surface analysis under ambient and high-pressure conditions.
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 ...
AES operates on the principle of the Auger effect, named after the French physicist Pierre Auger. When a material's surface is bombarded with a beam of high-energy electrons or photons, it causes the ...
Graphene is a single-atom-thick carbon sheet discovered in 2004. The crucial question during graphene synthesis is, "How do I know that the material I'm making is actually single-atom thick?" Because ...
