摘要 In this review, we describe the principles of the tunnel junction, self-assembled monolayer (SAM) application techniques, experimental testbed fabrication, and characterization of the films and devices. In addition, techniques for directed application, removal, and functionalization of the monolayers are discussed. Bottom-up fabrication techniques have seen increased attention because of their versatility and ease of use. These films see mechanical uses as surface modifiers and micro-scale lubricants. Advances in nanowatt electronics and ultra-low power sensors have opened up an energy harvesting niche for solutions which would have proven ineffective just some years ago. The focus of this study is the two- terminal junction which has potential applications in THz rectification for energy harvesting, medical imaging, and defense sensing. The quantum theory of operation behind these devices is touched on briefly---describing tunneling through the organic monolayers. Commentary on trends in research and potential future work are presented as well. 在这评论,我们描述这些电影和设备的隧道连接,自我装配的单层(SAM ) 申请技术,试验性的试验床制造,和描述的原则。另外,为单层的指导申请,移动,和 functionalization 的技术被讨论。因为他们的通用性和容易使用,自底向上的制造技术看见了增加的注意。这些电影把机械使用看作表面修饰词和微规模的润滑剂。在 nanowatt 电子学和极端低的力量传感器的进展开创了为就一些年以前将证明无效的答案收获壁龛的一个精力。这研究的焦点是为精力收获,医药成像,并且防卫察觉到在 THz 校正有潜在的应用的二终端的连接。在这些设备后面的操作的量子论通过器官的单层在 brieflydescribing 通道上被摸。对在研究和潜在的未来工作的趋势的评论表现为很好。
