A unique and powerful tool for elemental depth profiling of thin films.

A heavy ion beam from Pelletron accelerator is guided to the sample to be studied. The velocity (TOF) and energy are measured in coincidence for forward scattered sample atoms and incident ions.

With TOF-ERDA spectrometer all sample atoms can be detected and used in quantitative depth profiling.

  • Quantitative analysis of all elements possible (including hydrogen)
  • Film thicknesses from 5 nm to 500 nm
  • Depth resolution even 1-2 nm at the surface
  • Sensitivity: down to 0.1 at.% or better
