Atom probe tomography reconstruction at a grain boundary in lightly doped solid electrolyte showing the 3D distribution of impurities in the sample. (Image: Northwestern University) APT is extensively ...

A recent article in Scientific Reports explored methods to optimize the preparation of atom probe tomography (APT ... at 36 million detected ions. Reconstruction and elemental analysis were ...

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 ...
