Status: current

Definition
Extended X-ray absorption fine structure spectroscopy in which, instead of measuring X-ray absorption, electron emission arising from that absorption is measured.

Notes
1) Emitted electrons include Auger electrons and secondary electrons.
2) The detection of emitted electrons provides greater surface sensitivity than is generally found with extended X-ray absorption fine structure measurements.
