CAMECA LEAP 5000 XS
Housed at the University of Alabama Central Analytical Facility.
The LEAP 5000 XS is a Local Electrode Atom Probe microscope which provides nano-scale surface, bulk and interfacial materials analysis of simple and complex structures with atom-by-atom identification and accurate spatial positioning. The system works using the principle of field evaporation, whereby a strong electric field applied to the specimen is sufficient to cause removal of atoms by ionization. Atom removal is triggered either via a voltage or laser pulse applied to the sample. The local electrode provides both ease of use and data quality as well as enabling the use of prefabricated Microtip arrays. Using these enables multiple analytical specimens to be prepared, mounted and loaded into the instrument for maximum efficiency with multi-user and/or multi-experiment scenarios. |
