Rutherford Backscattering Spectroscopy (RBS)

Rutherford Backscattering Spectroscopy (RBS)

  • The nondestructive and multielemental analysis technique 
  • Elemental composition (stoichiometry) without a standard (1 - 5% accuracy).
  • Elemental depth profiles with a depth resolution of 2 - 10 nanometers and a maximum depth of 2 - 20 microns. 
  • Surface impurities and impurity distribution in depth (sensitivity up to the sub-ppm range).
  • Elemental areal density and thus thickness (or density) of thin films if the film density (or thickness) is known.
  • Diffusion depth profiles between interfaces up to a few microns below the surface.
  • Channeling-RBS is used to determine the lattice location of impurities and defect distribution depth profile in single crystalline samples.
