Three‐Dimensional Atomic‐Scale Tomography of Buried Semiconductor Heterointerfaces

Advanced Materials Interfaces, 2023
Atom probes generate three‐dimensional atomic‐scale tomographies of material volumes corresponding to the size of modern‐day solid‐state devices. Here, the capabilities of atom probe tomography are evaluated to analyze buried interfaces in semiconductor ...

Spinodal decomposition in alkali feldspar studied by atom probe tomography. [PDF]

Phys Chem Miner, 2020
: We used atom probe tomography to complement electron microscopy for the investigation of spinodal decomposition in alkali feldspar. To this end, gem-quality alkali feldspar of intermediate composition with a mole fraction of a(K) = 0.43 of the K end ...

Atom Probe Tomography of Lunar Regolith Ilmenite Grain Surfaces

, 2017
Here we demonstrate the use of atom probe tomography to characterize products of space weathering in Apollo 17 ilmenite soil samples. We find nanophase Fe particles, zoning, and vesicles that presumably once held noble gases from solar ...

Grain-boundary segregation of magnesium in doped cuprous oxide and impact on electrical transport properties

Scientific Reports, 2021
In this study, we report the segregation of magnesium in the grain boundaries of magnesium-doped cuprous oxide (Cu2O:Mg) thin films as revealed by atom probe tomography and the consequences of the dopant presence on the temperature-dependent Hall effect ...
