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…
3D oxygen vacancy order and defect-property relations in multiferroic (LuFeO)/(LuFeO) superlattices
K. A. Hunnestad, H. Das, C. Hatzoglou +7
Oxide heterostructures exhibit a vast variety of unique physical properties. Examples are unconventional superconductivity in layered nickelates and topological polar order in (PbT…
Optimizing compositional and atomic-level information of oxides in atom probe tomography
Kasper Hunnestad, Constantinos Hatzoglou, Francois Vurpillot +5
Atom probe tomography (APT) is a 3D analysis technique that offers unique chemical accuracy and sensitivity with sub-nanometer spatial resolution. Recently, there is an increasing…
Characterization of Pd and Pd@Au core-shell nanoparticles using atom probe tomography and field evaporation simulation
Se-Ho Kim, Kyuseon Jang, Phil Woong Kang +6
We report on atom probe tomography analyses of Pd and Pd@Au nanoparticles embedded in a Ni matrix and the effects of local evaporation field variations on the atom probe data. In o…
Preferential evaporation in atom probe tomography: an analytical approach
Constantinos Hatzoglou, Solène Rouland, Bertrand Radiguet +5
Atom probe tomography (APT) analysis conditions play a major role in the composition measurement accuracy. Preferential evaporation, which significantly biases apparent composition…
