ABSTRACT Molecular transistors have been extensively investigated as the building blocks for the ultimate miniaturization of electronic devices. They are assembled from single molecules and molecular monolayers serving as a current-carrying channel in a conventional field-effect transistor configuration, in which gate electrodes have been electrically or electrochemically implemented in several types of test beds such as electromigration junctions, mechanically controllable break junctions, and devices with carbon-based electrodes. The energy level alignments of the component molecules incorporated into the transistor can be tuned using molecular orbital gating and it can ultimately control the flow of charge carriers. Herein, we review recent progress in studying spectroscopic characterization techniques and charge transport properties of molecular transistors.

分子晶体管的光谱询问和电荷传输特性

摘要 分子晶体管作为电子设备最终小型化的构建模块已被广泛研究。它们由单分子和分子单层组装而成，用作传统场效应晶体管配置中的载流通道，其中栅电极已在几种类型的测试台中以电或电化学方式实现，例如电迁移结、机械可控断裂结，以及带有碳基电极的设备。结合到晶体管中的组成分子的能级排列可以使用分子轨道门控进行调整，它可以最终控制电荷载流子的流动。在此处，
