For the first time, researchers have been able to measure the quantum state of electrons ejected from atoms that have ...

The photoelectric effect, first explained by Albert Einstein in 1905, laid the foundation for quantum mechanics. It occurs when high-energy light strikes atoms, releasing electrons. This phenomenon is ...

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 ...

XPS relies on the photoelectric effect, where irradiating a material with X-rays causes the emission of core electrons. The kinetic energy of these emitted electrons is measured, which can be directly ...

X-ray photoelectron spectroscopy is a common surface analysis method because it can be used on a wide variety of materials and supplies valuable quantitative and chemical data. X-ray photoelectron ...

Scientists in Korea using 2D semiconducting materials discovered a new quantum state that could pave the way for more ...

The PHI 5800 X-ray photoelectron spectrometer (XPS) is equipped with a dual source anode (Al and Mg), a hemispherical analyzer for XPS and Auger electron spectroscopy (AES) analysis, including ...

X-ray Photoelectron Spectroscopy (XPS)is a highly sensitive technique for identifying and quantifying the chemical states of elements on the outermost surface of a solid. It is especially useful for ...

X-ray Photoelectron Spectroscopy (XPS) is one of the most popular surface analysis methods because it can be used on a broad range of materials and it supplies highly useful chemical data on the ...
