The past two decades have witnessed increasingly rapid advances in the field of single-molecule electronics, which are expected to overcome the limitation of the miniaturization of silicon-based microdevices, thus promoting the development of device manufacturing technologies and characterization means. In addition to this, they can enable us to investigate the intrinsic properties of materials at the atomic- or molecular-length scale and probe new phenomena that are inaccessible in ensemble experiments. In this perspective, we start from a brief introduction on the manufacturing method of graphene-molecule-graphene single-molecule junctions (GMG-SMJs). Then, we make a description on the remarkable functions of GMG-SMJs, especially on the investigation of single-molecule charge transport and dynamics. Finally, we conclude by discussing the main challenges and future research directions of molecular electronics.
在过去的二十年里,单分子电子学领域取得了越来越迅速的进展,预计这些进展将克服硅基微器件小型化的局限性,从而推动器件制造技术和表征手段的发展。除此之外,它们能使我们在原子或分子长度尺度上研究材料的固有特性,并探测在系综实验中无法获得的新现象。从这个角度出发,我们首先简要介绍石墨烯-分子-石墨烯单分子结(GMG-SMJs)的制造方法。然后,我们描述GMG-SMJs的显著功能,特别是在单分子电荷传输和动力学研究方面。最后,我们通过讨论分子电子学的主要挑战和未来研究方向来进行总结。
