Application software for data analysis for three-dimensional atom probe microscopy
نویسندگان
چکیده
We present a custom MacOS-based application, ADAM, for analysis of data collected by a three-dimensional atom probe (3DAP). The application is designed to carry out a common set of analysis tasks, to be customizable, to provide easy export and import of data, and to be simple enough for novice users to understand quickly. The integration of both graphical (GUI) and scripting (SUI) user interfaces and the functionality accessible from both is discussed. Different types of visualization can be used for best presentation of 3DAP data. © 2002 Elsevier Science B.V. All rights reserved.

Atom scale characterization of the near apex region of an atomic force microscope tip.
Three-dimensional atom probe tomography (APT) is successfully used to analyze the near-apex regions of an atomic force microscope (AFM) tip. Atom scale material structure and chemistry from APT analysis for standard silicon AFM tips and silicon AFM tips coated with a thin film of Cu is presented. Comparison of the thin film data with that observed using transmission electron microscopy indicate...

The availability of reliable and well-engineered commercial instruments and data analysis software has led to development in recent years of robust and ergonomic atom-probe tomographs. Indeed, atom-probe tomography (APT) is now being applied to a broader range of materials classes that involve highly important scientific and technological problems in materials science and engineering. Dual-beam...
متن کاملNanoscale Microstructural Analyses by Atom Probe Field Ion Microscopy
Recent progress in atom probe field ion microscopy (APFIM) and its applications to nanoscale microstructural studies of metallic materials are reviewed. By employing a three dimensional atom probe (3DAP), it is possible to map out elemental distributions in the real space with almost an atomic resolution, and chemical analysis of interfaces and nanoparticles can be made with improved accuracy i...
متن کاملFirst data from a commercial local electrode atom probe (LEAP).
The first dedicated local electrode atom probes (LEAP [a trademark of Imago Scientific Instruments Corporation]) have been built and tested as commercial prototypes. Several key performance parameters have been markedly improved relative to conventional three-dimensional atom probe (3DAP) designs. The Imago LEAP can operate at a sustained data collection rate of 1 million atoms/minute. This is ...
متن کاملProgress of Three-dimensional Atom Probe Techniques for Analysis of Steel Materials —Development of Atom Probe Specimen Preparation Techniques for Site-specific Regions—
Three-dimensional atom probe (3DAP) is a very powerful tool which can investigate atomic positions of all alloying elements in steel with lattice-spacing spatial resolution. However, the very small analysis volume of 3DAP has limited its application field. To meet the needs for atomic-scale analyses of steel materials, advanced preparation techniques of a needle specimen tip including a site-sp...
