通过单壁碳纳米管（SWNT）的纵向解链成功合成了石墨烯纳米带（GNR）。在此过程中，进行短时超声处理以解压缩 SWNT。所得结果清楚地表明合成的 GNR 具有半导体性。此外，拉曼光谱还证实，样品在解压过程中的时间变化存在快反应和慢反应两种类型。此外，所获得的结果证实，较窄的单壁碳纳米管应该快速解开，而较宽的单壁碳纳米管应该缓慢解开。 (C) 2017 日本应用物理学会
Graphene nanoribbons (GNRs) were successfully synthesized by the longitudinal unzipping of a single-walled carbon nanotube (SWNT). In this process, a short-duration sonication was performed to unzip the SWNT. The obtained results clearly show that the synthesized GNR is semiconducting. Furthermore, it is also confirmed by Raman spectroscopy that the time variation of the samples during the unzipping process has two types of reaction, namely, fast and slow. Furthermore, the obtained results confirm that the narrower SWNT should be unzipped quickly, whereas the wider SWNT should be unzipped slowly. (C) 2017 The Japan Society of Applied Physics
