Abstract

Atom probe tomography (APT) is a powerful analytical technique whose strengths lie in its combination of three-dimensional reconstructions, (sub)nanometer spatial resolution, and nominally equal sensitivity to all elements across the periodic table. An additional strength of APT, at least in most cases, is its ability to measure local composition and composition variations with good yet typically ill-defined quantitative accuracy. Experienced researchers know that maximizing this accuracy requires some exploration of analysis conditions to understand quantitatively how the measured composition varies, followed by rigorous data treatment that, ideally, results in some estimate of a give measurement's quantitative uncertainty.
