XPS

Description: Kratos Axis Supra x-ray photoelectron spectrometer
Location: Chapman Hall - 030C
Uses:

Allows the user to determine the elemental composition of the top ~10 nm of the sample surface.

Specifications:

The Kratos Axis Supra x-ray photoelectron spectrometer (XPS) is equipped with monochromatic Al and Ag sources, and includes the Brite source for higher signal small spot spectroscopy. A helium lamp is included for ultraviolet photoelectron spectroscopy (UPS) work. The ion gun for sputtering is capable of delivering traditional Ar+ ions and also gas cluster argon ions for more gentle sputtering resulting in less sample damage. An air sensitive sample holder allows samples to be transferred from a third party glove box to the entry port of the XPS without exposure to air.
