摘要

摘要: 窄石墨烯纳米带（GNR）因具有较大带隙使其在电子和光电器件中有广阔的应用前景。然而目前仍缺乏良好的方法来制备高质量、窄GNR。本文研发了一种过渡金属轴向解链单壁碳纳米管（SWCNT）制备窄的高质量GNR和GNR/SWCNT分子内异质结的方法。通过研究，获得了该方法解链SWCNT的最佳工艺，通过控制H₂流量能调节SWCNT的解链速率。窄GNR和GNR/SWCNT分子内异质结有望被用于下一代电子和光电器件。

Abstract: Narrow graphene nanoribbons (GNRs) have great prospects for use in electronic and optoelectronic devices owing to their sizable band gap. However, there has been no good way to prepare high-quality GNRs with a narrow width. Here, a method is reported to prepare narrow, high-quality GNRs and single-wall carbon nanotube (SWCNT)/GNR intramolecular heterojunctions by the metal-catalyzed axial unzipping of SWCNTs, using sputtered Pd as the catalyst at 750 and 800 ℃ under a mixed gas flow of Ar and H₂. The unzipping process parameters were optimized. It was found that the unzipping rate of SWCNTs can be adjusted by controlling the hydrogen flow rate. The prepared narrow GNRs and GNR/SWCNT intramolecular heterojunctions are promising for use in next-generation electronic and optoelectronic devices.
