摘要

自组装单分子层(SAM)是一种二维分子集合体。在分子电子学中,SAMs 是探索结构-隧道关系的活跃元件,因为它们的制造和原子细化(超)分子修饰都非常容易和简单。单组分纯 SAM 通常被集成到隧道结中。然而,纯 SAM 在一定程度上存在缺陷,导致击穿电压较低,从而使窄小的偏置窗口无法通过结。狭窄的偏置窗口最终将可能的电荷传输通道限制在浅分子轨道能级上,如最高占据分子轨道(HOMO)或最低未占据分子轨道(LUMO),从而难以研究通过更深分子轨道(MO)能级(如亚 HOMO 和后 LUMO)的电荷传输。

Electrically Stable Self-Assembled Monolayers Achieved through Repeated Surface Exchange of Molecules
Self-assembled monolayers (SAMs) are two-dimensional molecular ensembles. In molecular electronics, SAMs serve as active components for exploring structure-tunneling relationships due to their easy and simple fabrication and atomic-detailed (supra)molecular modifications. Single-component pure SAMs are commonly incorporated into tunneling junctions. However, pure SAMs are defective to some extent, which results in low electrical breakdown voltages and allows access to narrow bias windows through the junctions. Narrow bias windows ultimately limit the possible charge-transport channels to shallow molecular orbital energy levels such as the highest occupied molecular orbital (HOMO) or lowest unoccupied molecular orbital (LUMO), making it difficult to investigate charge transport through deeper molecular orbital (MO) energy levels such as sub-HOMOs and post-LUMOs.
