Over the past decades, construction of nanoscale electronic devices with novel functionalities based on low-dimensional structures, such as single molecules and two-dimensional (2D) materials, has been rapidly developed. To investigate their intrinsic properties for versatile functionalities of nanoscale electronic devices, it is crucial to precisely control the structures and understand the physical properties of low-dimensional structures at the single atomic level. In this review, we provide a comprehensive overview of the construction of nanoelectronic devices based on single molecules and 2D materials and the investigation of their physical properties. For single molecules, we focus on the construction of single-molecule devices, such as molecular motors and molecular switches, by precisely controlling their self-assembled structures on metal substrates and charge transport properties. For 2D materials, we emphasize their spin-related electrical transport properties for spintronic device applications and the role that interfaces among 2D semiconductors, contact electrodes, and dielectric substrates play in the electrical performance of electronic, optoelectronic, and memory devices. Finally, we discuss the future research direction in this field, where we can expect a scientific breakthrough.
在过去几十年中，基于低维结构（如单分子和二维（2D）材料）构建具有新颖功能的纳米级电子器件得到了迅速发展。为了研究纳米级电子器件多功能性的内在特性，在单原子水平上精确控制结构并理解低维结构的物理性质至关重要。在这篇综述中，我们全面概述了基于单分子和二维材料的纳米电子器件的构建及其物理性质的研究。对于单分子，我们专注于通过精确控制其在金属基板上的自组装结构和电荷传输特性来构建单分子器件，如分子马达和分子开关。对于二维材料，我们强调其在自旋电子器件应用中的自旋相关电输运特性，以及二维半导体、接触电极和介电基板之间的界面在电子、光电子和存储器件的电性能中所起的作用。最后，我们讨论了该领域未来的研究方向，有望在其中取得科学突破。
