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.
The photoelectric effect, first explained in 1905, transformed our understanding of how light interacts with matter. When ...
In ultraviolet photoelectron spectroscopy (UPS), UV photons are used to eject an electron from the graphene, which can only eject an electron from the valence band because of their limited depth of ...
Ultraviolet Photoelectron Spectroscopy (UPS) Ultraviolet photoelectron spectroscopy (UPS) is often used in conjunction with XPS and for the same types of materials and applications as XPS. However, it ...
RECENTLY vacuum ultraviolet photoelectron spectroscopy, using helium 21.2 eV radiation, has become of great value in examining ionization of compounds in the gas phase1. If the technique could be ...
