Technique X-Ray Photoelectron Spectroscopy (XPS)

Basic Capabilities

X-Ray Photoelectron Spectroscopy provides information about the elemental and chemical composition of a surface, determine the surface concentration of elements, chemical states, molecular environment and/or oxidation state of metals


Equipment Make Kratos
Equipment Model AXIS-165


Advantage of Technique/Equipment

Surface sensitive top ~10 nm, can detect all elements except H and He, sensitive to differences in chemical environments, quantitative without using standards, use conducting and insulting samples

Limitations of Technique/Equipment Samples need to be vacuum compatible, detection limit~ 0.1atomic %
