Information processing using molecular junctions is becoming more important as devices are miniaturized to the nanoscale. Herein, we report functional molecular junctions derived from double self-assembled monolayers (SAMs) intercalated between soft graphene electrodes. Newly assembled molecular junctions are fabricated by placing a molecular SAM/(top) electrode on another molecular SAM/(bottom) electrode by using a contact-assembly technique. Double SAMs can provide tunneling conjugation across the van der Waals gap between the terminals of each monolayer and exhibit new electrical functions. Robust contact-assembled molecular junctions can act as platforms for the development of equivalent contact molecular junctions between top and bottom electrodes, which can be applied independently to different kinds of molecules to enhance either the structural complexity or the assembly properties of molecules.
随着器件被小型化到纳米尺度，利用分子结进行信息处理变得越来越重要。本文报道了源自软石墨烯电极之间夹层的双自组装单层（SAM）的功能分子结。通过使用接触组装技术，将分子 SAM/（顶）电极放置在另一分子 SAM/（底）电极上，可制造出新的组装分子结。双 SAM 可以提供贯穿各单层末端范德华间隙的隧穿共轭，并表现出新的电学功能。稳固的接触组装分子结可用作顶部和底部电极之间等效接触分子结的开发平台，可以独立应用于不同类型的分子，以增强分子的结构复杂性或组装特性。
