摘要
有机分子层的电输运特性是分子电子学研究的重要问题.镓铟合金电极技术具有成结率高、可靠性好及操作简便等优点,近年来已成为测量单分子层电输运的常用表征手段.本文介绍了镓铟合金电极技术的基本原理及测试方法,综述了该技术所带来的一些前沿成果,并对其目前存在的优势、缺点及未来发展前景进行了分析.
Electron transport through organic molecular layers is an essential issue in molecular electronics.The electrical testing by employing gallium-indium alloy(EGaIn)electrodes is well recognized because of its high junction formation rate,reliability,and user-friendly operation.It thus has been extensively adopted in analyzing the charge transport through self-assembled monolayers(SAMs).This review outlines the principle and experimental operation of the EGaIn technique,introduces the recent progress in molecular electronics using the EGaIn technique,and finally gives a prospect.
