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…
Atomic-scale 3D imaging of individual dopant atoms in a complex oxide
K. A. Hunnestad, C. Hatzoglou, Z. M. Khalid +6
A small percentage of dopant atoms can completely change the physical properties of the host material. For example, chemical doping controls the electronic transport behavior of se…
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…
