[SXES] Soft X-ray Emission Spectroscopy

SXES is a method that evaluates the chemical bonding state using soft X-rays emitted from materials.

- It is possible to evaluate the chemical bonding states focusing on specific elements in the sample (especially light elements such as B, C, N, O). - The spectral shape reflects the partial density of states of the targeted elements in the valence band. - Evaluation of the band structure is also possible through simultaneous measurement with X-ray absorption spectroscopy (XAS). - Since information from the bulk is obtained, it is less affected by the influence of the surface region within a few nanometers. - Evaluation can be performed without being affected by charging effects, even for insulators. - The detection limit is low (<1 atomic%), allowing for the evaluation of trace components.
