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 ...

Ultraviolet Photoelectron Spectroscopy (UPS): UPS utilizes ultraviolet photons (typically from a He discharge lamp) to investigate the valence band structure and electronic properties of materials.

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 ...

In situ, X-ray photoelectron spectroscopy (in situ XPS) and ultraviolet photoelectron spectroscopy (UPS) experiments provided ...

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 ...

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 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 ...

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 ...
