Study of fundamental properties arising from graphene edgestates

制备了细长形状的石墨烯样品（石墨烯纳米带：GNR），并通过拉曼光谱进行了检测。拉曼光谱分为两组，这取决于单个样品。光谱的差异是由边缘结构的差异引起的。值得注意的是，没有D带峰的GNR样品是具有长锯齿形边缘结构的GNR。

Graphene samples of long and narrow shape(graphene nannoribbons : GNR) were prepared and inspected by Raman spectroscopy. The Raman spectra were classified into two groups, depending on individual samples. The difference in the spectrum is caused by the difference in the edge structures. It is remarkable that the GNR samples whose D band peak is absent are GNRs with long zigzag edge structure.
