Abstract

Recent advances in self-assembled monolayers (SAMs) have overcome longstanding stability challenges, unlocking new opportunities for molecular-scale devices in quantum transport applications. This review highlights key developments focused on enhancing the electrical and thermal robustness of SAMs. The Repeated Surface Exchange of Molecules (ReSEM) method significantly improves breakdown voltages by mixing two molecular species to reduce packing defects and nanoscale pinholes, enabling access to deeper molecular orbital energy levels. Additionally, N-heterocyclic carbene (NHC) anchor groups deliver exceptional thermal stability, sustaining consistent thermoelectric performance at temperatures up to 573 K. These breakthroughs expand the functional versatility of SAM-based molecular junctions, paving the way for their integration into practical electronic, thermoelectric, and sensing technologies.

在量子输运应用中增强单层膜的稳定性

自组装单层（SAMs）的最新进展克服了长期存在的稳定性挑战，为量子传输应用中的分子尺度器件带来了新的机遇。这篇综述强调了在增强地对空导弹的电和热稳健性方面的关键进展。分子重复表面交换（ReSEM）方法通过混合两种分子来减少包装缺陷和纳米级针孔，从而显著提高击穿电压，从而可以进入更深的分子轨道能级。此外，n -杂环碳（NHC）锚基团具有优异的热稳定性，在高达573 K的温度下保持一致的热电性能。这些突破扩展了基于sam的分子结的功能多功能性，为它们集成到实用的电子、热电和传感技术中铺平了道路。
