用高分辨率非接触原子力显微镜(NC-AFM)和尖端增强拉曼光谱(TERS)研究了在Ag(110)衬底上自组装的硅纳米带和魔术团簇的原子结构。直观地显示了硅纳米带和团簇中的五角环结构。此外，由亚纳米分辨率仪提取的单个Si纳米带和团簇的振动指纹证实了Si纳米带和团簇的五角形性质。这项工作表明，硅五边形可以成为构建硅纳米结构的重要元素，这可能会在未来基于硅的纳米电子器件中找到重要的应用。
The atomic structures of self-assembled silicon nanoribbons and magic clusters on Ag(110) substrate have been studied by high-resolution noncontact atomic force microscopy (nc-AFM) and tip-enhanced Raman spectroscopy (TERS). Pentagon-ring structures in Si nanoribbons and clusters have been directly visualized. Moreover, the vibrational fingerprints of individual Si nanoribbon and cluster retrieved by subnanometer resolution TERS confirm the pentagonal nature of both Si nanoribbons and clusters. This work demonstrates that Si pentagon can be an important element in building silicon nanostructures, which may find important applications for future nanoelectronic devices based on silicon.
