摘要

理解和调整单分子上的电荷输运是分子电子学的一个基本课题。由连接在两个电极上的单个分子组成的单分子结是单分子电荷传输研究中最常见的组成部分。在过去的二十年中,单分子结的快速技术和理论进步增加了我们对分子器件的电导特性和功能的理解。本文首先介绍了单分子结中电荷输运的基本原理,然后综述了通过电场和电位、光、机械力、热和化学环境等外部刺激调节单分子输运的最新进展。最后,我们讨论了分子电子学面临的挑战,并对未来的发展提出了看法。

Modulating single-molecule charge transport through external stimulus

Modulating single-molecule charge transport through external stimulus

Understanding and tuning charge transport over a single molecule is a fundamental topic in molecular electronics. Single-molecule junctions composed of individual molecules attached to two electrodes are the most common components built for single-molecule charge transport studies. During the past two decades, rapid technical and theoretical advances in single-molecule junctions have increased our understanding of the conductance properties and functions of molecular devices. In this perspective article, we introduce the basic principles of charge transport in single-molecule junctions, then give an overview of recent progress in modulating single-molecule transport through external stimuli such as electric field and potential, light, mechanical force, heat, and chemical environment. Lastly, we discuss challenges and offer views on future developments in molecular electronics.
