Photoelectrons 10 are taken into the energy analyzer 11 for a minute time DELTAtau after a predetermined delay time tau from an outer disturbance pulse 12, thereby to detect an energy spectrum. Because of the sweeping of the delay time tau, transient change of a surface state of the sample...
A photoelectron spectrum is recorded by counting ejected electrons over a range of kinetic energies. The energies and intensities of the photoelectron peaks enable identification and quantification of all surface elements (except hydrogen).Surface characterization The surface represents a discontinuity between...
X-ray Photoelectron Spectrometry (XPS) helps scientists understand the surface chemistry of materials, and it can used to explore nearly every element, with the exception of hydrogen and helium. By clicking on different elements on theXPS periodic tableon ourXPS Simplifiedwebpage, researchers can ob...
