Molecular Reaction Imaged by Scanning Atom Probe

Abstract

Organic molecule system supported on metal substrate was analyzed by atom probe with two-dimensional ion detector and scanning extractor electrode (3D-SAP). The comparison of angular distribution of detected ions between molecular system and common metal tip showed a significant difference when AP analysis was performed by voltage pulsing. The influence of catalytic property of metal substrate also demonstrated by changing the substrate material. [DOI: 10.1380/ejssnt.2010.69]
