Devaraj and others in the field turn instead to a technology called atom probe tomography (APT). APT uses either ultrafast electrical or laser pulses, depending on whether the sample under ...

However, for practical purposes, a probe that small will be able to gather little to no actual information once it arrives there—it's more of a feat of engineering rather than an actual ...

A recent article in Scientific Reports explored methods to optimize the preparation of atom probe tomography (APT) specimens for low-melting solder materials (96.5 wt.% Sn–3.0 wt.% Ag–0.5 wt.% ...
