X-ray Photoelectron Spectroscopy (XPS Analysis), also known as Electron Spectroscopy for Chemical Analysis (ESCA), is used to determine quantitative atomic composition and chemistry. It is a surface analysis technique with a sampling volume that extends from the surface to a depth of approximately 50-70 Angstroms. Alternatively, XPS analysis can be utilized for X-ray Photoelectron Spectroscopy (XPS) or Electron Spectroscopy for Chemical Analysis (ESCA) from Evans Analytical Group (EAG).sputter depth profiling to characterize thin films by quantifying matrix-level elements as a function of depth.
