Atom Probe Tomography: 3D Imaging at the Atomic Level

2011
Atom probe tomography (APT) is the only approach able to map out the 3D distribution of chemical species in a material at the atomic-scale. The instrument provides quantitative measurements of local chemical composition in a small selected volume at the nm scale. The in-depth spatial resolution reaches a few tens of picometres enabling atomic layers to

Atom probe tomography of isoferroplatinum

American Mineralogist, 2015
Here we apply the relatively new analytical technique of atom probe tomography (APT) to a naturally occurring isoferroplatinum grain (Pt3Fe) from northern California to constrain its origin and the nanoscale distribution of trace elements within the grain.

Atom Probe Tomography 2012

Annual Review of Materials Research, 2012
In the world of tomographic imaging, atom probe tomography (APT) occupies the high-spatial-resolution end of the spectrum. It is highly complementary to electron tomography and is applicable to a wide range of materials. The current state of APT is reviewed.

An Atom-Probe Tomography Primer

MRS Bulletin, 2009
AbstractAtom-probe tomography (APT) is in the midst of a dynamic renaissance as a result of the development of well-engineered commercial instruments that are both robust and ergonomic and capable of collecting large data sets, hundreds of millions of atoms, in short time periods compared to their predecessor instruments.

Atom Probe Tomography of Encapsulated Hydroxyapatite Nanoparticles

Small Methods, 2020
AbstractHydroxyapatite nanoparticles (HAP NPs) are important for medicine, bioengineering, catalysis, and water treatment. However, current understanding of the nanoscale phenomena that confer HAP NPs their many useful properties is limited by a lack of information about the distribution of the atoms within the particles.

Laser Atom Probe Tomography: some applications

2006 19th International Vacuum Nanoelectronics Conference, 2006
Laser atom probe tomography was used to investigate the inter-diffusive reactions at the silicon-nickel interface. The early stages of formation of a NiSi silicide was studied. The addition of Pt was shown to increase the temperature of formation of the high resistivity NiSi2 phase by approximately 150 ...

Atom Probe Tomography of Nanowires

2015
Abstract Atom probe tomography (APT) is a destructive material characterization technique that can analyze the composition of small volumes (~ 100 × 100 × 100 nm 3 ) of a sample with subnanometer resolution and part per million sensitivity. APT is therefore well suited to investigate semiconductor nanostructures in order to relate growth conditions ...

Spatial Distribution Maps for Atom Probe Tomography

Microscopy and Microanalysis, 2007
A real-space technique for finding structural information in atom probe tomographs, spatial distribution maps (SDM), is described. The mechanics of the technique are explained, and it is then applied to some test cases. Many applications of SDM in atom probe tomography are illustrated with examples including finding crystal lattices, correcting lattice
