“…The contrast effects obtained from the 3D exploration of the volume are generally easier to interpret, as sections or slices may be taken using any direction into the material. Improvements of the algorithm, using a variable radius of curvature in parallel with the number of images are being concurrently developed (Rademacher et al, 2009; Semboshi et al, 2009). The ability to provide a 3D image of precipitates, when a high contrast difference is found between precipitates and matrix, was demonstrated for small carbide precipitates in steels (Akré et al, 2009), in core–shell precipitates in Al–Sc–Zr alloys (Van Tendeloo et al, 2012), and in Cu–Ti or Cu–Fe alloys (Rademacher et al, 2009; Semboshi et al, 2009).…”

“…It was also demonstrated that even small precipitates with small differences in contrast compared with the matrix may be readily reconstructed in 3D. The precipitate size distributions and 3D morphologies of precipitates are determined in a straightforward manner without the necessity for complex interpretations (Akré et al, 2009; Rademacher et al, 2009; Semboshi et al, 2009; Cazottes et al, 2012). Image distortions are generally less severe than in APT reconstructions.…”

True Atomic-Scale Imaging in Three Dimensions: A Review of the Rebirth of Field-Ion Microscopy

This article reviews recent advances utilizing field-ion microscopy (FIM) to extract atomic-scale three-dimensional images of materials. This capability is not new, as the first atomic-scale reconstructions of features utilizing FIM were demonstrated decades ago. The rise of atom probe tomography, and the application of this latter technique in place of FIM has unfortunately severely limited further FIM development. Currently, the ubiquitous availability of extensive computing power makes it possible to treat and reconstruct FIM data digitally and this development allows the image sequences obtained utilizing FIM to be extremely valuable for many material science and engineering applications. This article demonstrates different applications of these capabilities, focusing on its use in physical metallurgy and semiconductor science and technology.

“…Various algorithms have been developed specifically for atom-probe analysis (Ceguerra et al, 2010;Hyde and English, 2001;Rademacher et al, 2009;Slabanja et al, 2007;Stephenson et al, 2007;Vaumousse et al, 2003) to identify individual clusters and these clusters are often taken to be representative of those existing in the original specimen. They produce a classification that assigns every solute atom to a particular cluster.…”

A limiting characteristic of the atom-probe technique is the nondetection of ions and this embodies a significant "missing information" problem in investigations of atomic clustering phenomena causing difficulty in the interpretation of any atom-probe experiment. It is shown that the measurable cluster-size distribution can be modeled by a mixed binomial distribution. A deconvolution method based upon expectation-maximization (EM) algorithm is presented to obtain the original physical distribution from an efficiency-degraded distribution, thereby providing means to calculate accurate cluster number densities from atom probe results. The accuracy of this restoration was predominantly dependent upon the detector efficiency and was proved to be highly accurate in the case of conventional atom-probe detector efficiencies (ε = 57%). Such considerations and measures are absolutely necessary when the number density of clusters and small precipitates is in any way regarded as important. We conclude that limitations in detector efficiency are more limiting for cluster-finding analyses via atom-probe techniques than spatial resolution issues, and therefore the current endeavors for improving detector technologies are well found.
