Performing X-ray photoelectron spectroscopy with ungrounded samples requires additional considerations to avoid spectra ...

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 ...

For the first time, and contrary to popular belief, scientists measured the vibrational structure of hydrogen and helium atoms by X-rays. The results disprove the misconception that it’s impossible to ...

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 ...

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 ...

X-rays, a type of electromagnetic radiation with wavelengths from 0.01 to 10 nanometers, pack enough energy to pierce materials and interact with inner-shell electrons. 1 When they hit a sample, ...
