The atom probe can generate atom-scale 3D reconstructions of a region of interest, providing chemical and isotopic information at nanometre length scales.

  • Spatial resolution: ~ 1nm
  • Field of view: > 500nm along specimen axis, >100nm laterally
  • Mass resolution: >1000 (M/∆MFWHM)
  • Chemical sensitivity: ~ 10ppm
  • Atomic detection efficiency: ~37%, with equal sensitivity to all ion species, from H+ to large molecular ion complexes
