XPS – X-ray photoelectron spectroscopy

X-rays generate electrons only from the near surface (~5nm), alowing for extreme surface analysis. Moreover, photoelectron energy is element specific.

The OCAS XPS is equipped with a mono-chromatic Al X-ray source; a neutraliser; depth-profiling and angle-resolved capabilities.

 Typical examples of use

  • study of passivation layers
  • surface contamination analysis
  • thin film or nano-coating analysis 
  • adhesion phenomena
