Atom probe tomography allows for three-dimensional reconstruction of the elemental
distribution in materials at the nanoscale. However, the measurement of the chemical …

A B-spline version of a general Dirac–Hartree–Fock program is described. The usual
differential equations are replaced by a set of generalized eigenvalue problems of the form …

A systematic study of the biases occurring in the measurement of the composition of GaN by
Atom Probe Tomography was carried out, in which the role of surface electric field and laser …

The application of a high electrostatic field at the apex of monocrystalline diamond
nanoscale needles induces an energy splitting of the photoluminescence lines of color …

This paper describes initial experimental results from an extreme ultraviolet (EUV) radiation-
pulsed atom probe microscope. Femtosecond-pulsed coherent EUV radiation of 29.6 nm …

Current imaging algorithms in atom probe tomography (APT) assume a simple geometric
model for the trajectories of evaporated ions between the emitter and detector. Such point …

Specimen survivability is a primary concern to those who utilize atom probe tomography
(APT) for materials analysis. The state-of-the-art in understanding survivability might best be …

The thermal properties of single-crystal diamond nanowires (NWs) have been calculated
from first principles but have never been measured experimentally. Taking advantage of the …

This paper demonstrates the increased light absorption efficiency of semiconducting atom
probe tips resulting from focused-ion-beam (FIB) preparation. We use transmission electron …

In atom probe tomography (APT), accurate reconstruction of the spatial positions of field
evaporated ions from measured detector patterns depends upon a correct understanding of …
