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 ...

Researchers have improved an ambient-pressure photoelectron spectroscopy instrument using hard X-rays and succeeded in photoelectron spectrometry under real atmospheric pressure for the first time in ...

Recently, ionic liquids have been recognized as the possible lubricants for metal/metal contacts. The wear and friction characteristics of the liquids are investigated using tribological experiments.

Ultrafast measurements reveal how light energy moves across two dimensional and organic semiconductor interfaces, enabling ...

The PHI VersaProbe XPS Microprobe is a multi-technique, ultra-high vacuum surface analysis instrument that is capable of producing focused, highly monochromatic X-ray beam that can be scanned over a ...

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-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 ...

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, ...
