Description
Atom probe tomography reconstructed data from APT specimen OREX-803469-108, analysed in laser-assisted mode. All valid APT data is included, using an extended (Epos) data format that allows generation of alternative spatial reconstructions if required. This data set contains a moderate amount of 69Ga contamination near the specimen surface, and approximately 100 nm into the reconstruction on one side, due to ion implantation during specimen preparation with a monoisotopic 69Ga+ focussed ion beam. The data indicates a combination of pentlandite and pyrrhotite mineral phases. The pentlandite mineral contains several one-dimensional features enriched in Na and OH2. The reconstruction was performed using the voltage to model the specimen radius. A mass range definition file is included with all identified mass peaks.
