摘　　要：近年来,在分子电子学这一新型交叉领域中不断涌现出一些新的实验和理论研究进展.本文在简要介绍分子电子学中目前常用的实验技术、主要的电子输运和热电输运理论之后,重点列举了一些分子整流、分子开关、负微分电阻、自旋过滤、分子场效应管等功能型分子器件的研究实例,最后对分子电子学的发展前景进行了展望.The concept of using single molecules as building blocks for electronic components, i.e. diodes and transistors, at the molecular scale has been well established over the past years. Recently, many important experimental and theoretical progresses are emerging in molecular electronics. In the present work, through reviewing the current experimental techniques used to design and measure molecular devices as well as the popular theories adopted to describe the transport properties through single molecules, we highlight the latest functional molecular devices, including molecular rectifier, molecular switch, negative differential resistance, spin filter, and molecular transistor. Finally, we give a brief perspective about molecular electronics.
