I/V characteristics recorded in mechanically controllable break junctions revealed that field emission transport is enhanced in single molecule junctions as the gap size between two nanoelectrodes is reduced. This observation indicates that Fowler-Nordheim tunneling occurs not only for intermolecular but also for intramolecular electron transport driven by a reduced energy barrier at short tunneling distances.
在机械可控的断裂结中记录的 I/V 特性表明，随着两个纳米电极之间的间隙尺寸减小，场致发射输运在单分子结中得到增强。这一观察表明，Fowler-Nordheim 隧道不仅发生在分子间，而且也发生在由短隧道距离下降低的能量势垒驱动的分子内电子输运中。
