摘要：

Stable, single-molecule conducting-bridge configurations are typically identified from peak structures in a conductance histogram. In previous work on Pt with H-2 at cryogenic temperatures it has been shown that a peak near 1G(0) identifies a single-molecule Pt-H-2-Pt bridge. The histogram shows an additional structure with lower conductance that has not been identified. Here, we show that it is likely due to a hydrogen decorated Pt chain in contact with the H-2 molecular bridge.
