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 ...
New research from China reveals that ultraviolet degradation in TOPCon solar cells is governed by interface-level physical ...
Physicists achieve major leap in precision and accuracy at extremely low light levels. Researchers at the Max Planck Institute of Quantum Optics (MPQ) have successfully developed a new technique for ...
An ultraviolet photon-counting dual-comb spectrometer. Two ultraviolet frequency combs of slightly different pulse repetition frequencies are generated at very low light levels by nonlinear frequency ...
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 ...
Beamlines BL6U, BL7U, the newly constructed BL7U branch, and electron storage ring are highlighted in dotted lines. The upper (lower) left insetshows the photoelectron momentum pattern of the Au(111) ...
As the acronym suggests XPS (X-ray photoelectron spectroscopy) is a spectroscopic technique. An XPS spectrum is displayed as the number of photoelectrons collected by the detector as a function of ...
The solid electrolyte interphase (SEI) plays a pivotal role in governing the performance and stability of lithium (Li) batteries. X-ray photoelectron spectroscopy (XPS) is a powerful technique for ...
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 ...
