We have developed a combined surface-enhanced Raman spectroscopy (SERS) and break junction method to detect and characterize molecules between two microfabricated electrodes separated with a gap that can be continuously adjusted from a few angstroms to nanometers. It allows us to obtain a vibrational fingerprint of the adjustable molecular junction while performing electron transport measurements on the molecule simultaneously. This new approach will provide not only new insights into electron transport properties of molecule junctions on a chip but also the mechanism of single-molecule-SERS.
我们开发了一种结合表面增强拉曼光谱（SERS）和断结方法，用于检测和表征两个微加工电极之间的分子，这两个电极之间的间隙可以从几埃连续调节到纳米。它使我们能够在同时对分子进行电子传输测量时，获得可调节分子结的振动指纹。这种新方法不仅将为芯片上分子结的电子传输特性提供新的见解，还将为单分子SERS的机制提供新的见解。
