摘要: The implementation of fast pulsed laser has significantly improved the performance atom probe technique by enabling near-atomic-scale three-dimensional analysis poorly conducting materials. This broadened range applications for probe, addressing a major limitation technique. Despite this, implications lasing on tomographic reconstruction data have yet to be fully characterised. Here, we demonstrate how changes in shape specimen surface, induced pulsing, affect ion trajectories, and hence projection parameters used build map.
