The field of single molecule electronics has progressed remarkably in the past decades by allowing for more versatile molecular functions and improving device fabrication techniques. In particular, electrodes made from carbon-based materials such as graphene and carbon nanotubes (CNTs) may enable parallel fabrication of multiple single molecule devices. In this perspective, we review the recent progress in the field of single molecule electronics, with a focus on devices that utilizes carbon-based electrodes. The paper is structured in three main sections: (i) controlling the molecule/graphene electrode interface using covalent and non-covalent approaches, (ii) using CNTs as electrodes for fabricating single molecule devices, and (iii) a discussion of possible future directions employing new or emerging 2D materials.
在过去几十年里，单分子电子学领域取得了显著进展，这得益于实现了更多样化的分子功能并改进了器件制造技术。特别是，由石墨烯和碳纳米管（CNT）等碳基材料制成的电极，可能实现多个单分子器件的并行制造。从这个角度出发，我们回顾了单分子电子学领域的最新进展，重点关注使用碳基电极的器件。本文分为三个主要部分：（i）使用共价和非共价方法控制分子/石墨烯电极界面；（ii）使用碳纳米管作为电极制造单分子器件；（iii）讨论采用新型或新兴二维材料的可能未来方向。
