The electronic transport in single molecules, linked between a metallic substrate and a SNOM tip, will be studied by inelastic scattering methods

在两个金属电极之间通过自组装技术固定的单分子的电子传输测量证明了有机分子在纳米设备中作为功能部件的能力。原子尺度成像和操纵技术的最新发展和进步使人们能够进入单分子实验的新领域。特别是扫描近场光学显微镜，它能够以受控的方式将光场施加到分子系统中，从而扩大了金属锚定分子结的实验可用性质的范围。发展了一种用SNOM针尖接触单分子的新方法。同时已经证明，使用相同类型的四面体SNOM针尖在分子水平上吸附在Au上的拉曼光谱是可能的。我们建议将这两个实验结合起来，同时进行拉曼光谱和电导测量。对两个金属电极之间的分子的振动光谱的分析将验证所需的且仅存在所需的分子物种。这样的分析还将导致迄今尚未研究过的物理洞察。

Electronic transport measurements on single molecules which are immobilized by self-assembling techniques between two metallic electrodes proofed the ability of organic molecules to act as functional parts in nano-scale-devices. Recent developments and advances in atomic-scale imaging and manipulation techniques enables access to a new field of single molecule experiments. Especially scanning near field optical microcopy with its ability to apply an optical field to a molecular system in a controlled manner enlarges the range of experimentally available properties in metal-anchored molecular junctions. A novel method to contact single molecules with a SNOM-tip has been developed. In parallel it has been proofed, that Raman spectroscopy on a molecular level of adsorbates on Au using the same kind of tetrahedral SNOM-tip is possible. We propose to combine these two experiments to perform Raman spectroscopy and conductance measurements at the same time. Analysis of the vibrational spectrum of a molecule in between two metallic electrodes would verify that the desired and only the desired molecular species is present. Such an analysis would furthermore lead to physical insights that as far as known have not been studied yet.
