Local Electrode Atom Probe Microscopy: 3D Imaging and Analysis with True Atomic Resolution

摘要

The LEAP (Local Electrode Atom Probe) Microscope from Imago Scientific Instruments, Madison, WI, USA, provides spectacular new insights into the structure and composition of natural and artificial nanomaterials andnanostructures. Studies of microstruc-ture, impurity and solute distribution, precipitate composition as well as interface roughness and multilayer structure can be carried out on datasets containing the }D coordinates of each individual atom and its chemical identity within a specimen volume of approx. 100 nm lateral field of view and 100 nm depth.
