Atom probe tomography is without peer as a tool enabling the microscopic 3-D mapping of the location and chemistry of elements of the periodic table. The atom probe suite comprises two local electrode atom probes, the most recent acquisition being a laser-based platform that greatly expands the types of materials that can be characterised to include ceramics, semiconductors, organics, glasses, oxide layers, and even biological materials.

Capabilities LEAP:

Advanced atom probe instrument combining high speed acquisition and large field of view. For analysis of conducting and semiconducting materials.

  • Acquisition rate up to 107 ions per hour.
  • 106 - 3 x 107 atoms per specimen (typ.)
  • Analysis volume: 50 x 50 x 100nm (typ.)
  • Spacial resolution: 0.5nm
  • Mass resolution: 500

Capabilities LEAP3000:

The pulsed-laser system allows the 3-D analysis of composition and structure at atomic resolution in non-conductive systems such as ceramics, semiconductors, organics, glasses, oxide layers and even biological materials.

Example image

Three-dimensional atom probe image showing the layered spinodal nanostructure in a new ferrous intermetallic alloy. The solid volumes represent isoconcentration surfaces (i.e., surfaces of constant concentration) of the element nickel, indicating regions of the first spinodal phase. Sandwiched between two of these volumes are atoms of manganese and iron, which concentrate in the second spinodal phase.
