Spatial resolution(s) in atom probe tomography
Baptiste Gault, Frédéric De Geuser, Christoph Freysoldt +2
Atom probe tomography (APT) is often quoted to provide "atomic-scale" analysis of materials in three dimensions. Despite efforts to quantify APT's spatial resolution, misunderstand…
Exploring mechanisms leading to composition errors in monazite (CePO4) analysed with atom probe tomography
Tom Veret, Fabien Delaroche, Ivan Blum +6
Monazite (CePO4) is widely used in U-Th-Pb geochronology due to its reliable age determinations, although isotopic disturbances often require nanoscale investigation to better unde…
Stacking fault segregation imaging with analytical field ion microscopy
F. F. Morgado, L. T. Stephenson, S. Bhatt +8
Stacking faults (SF) are important structural defects that play an essential role in the deformation of engineering alloys. However, direct observation of stacking faults at the at…
Crystallographic dependence of Field Evaporation Energy Barrier in metals using Field Evaporation Energy Loss Spectroscopy mapping
François Vurpillot, Constantinos Hatzoglou, Benjamin Klaes +5
Atom probe tomography data is composed of a list of coordinates of the reconstructed atoms in the probed volume. The elemental identity of each atom is derived from time-of-flight…
