Electrical Characteristics of Tunneling Junctions Based on New Dithiophosphinic Acid Self-Assembled Monolayers and the Influence of Gold Substrate Morphology

我们的研究项目专注于分子电子学，这是一个令人兴奋的研究领域，因为这些设备有潜力超越传统半导体技术的规模限制。分子电子器件是其中至少一个器件尺寸为一个分子的厚度的器件。到目前为止，还没有商业上成功的分子电子器件；分子电子学的工作还处于基础研究阶段。我们的研究项目使用分子结测试结构来研究分子如何传递电子。我们设计和合成具有特定化学性质的新分子，这些分子将产生期望的电子功能。我们的基础研究将化学结构与电功能联系起来。最终，我们的研究计划旨在生产有用的分子线和开关，用于实际的分子电子器件。

Our research program focuses on molecular electronics, an exciting field of research due to the potential of these devices to surmount the scaling limits of conventional semiconductor technology. A molecular electronic device is one in which at least one of the device dimensions is the thickness of one molecule. As yet, there are no commercially successful molecular electronic devices; work in molecular electronics is in the fundamental research stage. Our research program uses a molecular junction test structure to investigate how molecules transport electrons. We design and synthesize new molecules with specific chemical properties that will produce desired electronic function. Our fundamental studies then correlate the chemical structure to the electrical function. Ultimately, our research program aims to produce useful molecular wires and switches for use in practical molecular electronic devices.
