XPS+UPS 1

Photoemission spectroscopy

XPS: Elemental surface composition (i.e. < top 10 nm), oxidation state, chemical bonding environment; UPS: Valence band edge

Sample conditions
Sample conditions Max. sample size: 25x27 mm²; solid samples (no powders, no liquids). It may not be possible to measure insulating samples/substrates.
What happens to the sample? Non invasive technique
