在此基础上,制备了1 nm薄碳纳米带和碳纳米环。芳香族自组装单分子膜通过电子束光刻局部交联成聚合物碳纳米片。在1200 K的真空中退火,将这些电绝缘纳米片转化为导电的二维相,由石墨烯纳米片组成,片电导率为100 - 2Ssq。该方法允许将图案直接写入单层中,从而允许无抗蚀剂制造厚度为1 nm的任意尺寸和形状的碳纳米结构。
The fabrication of 1nm thin carbon nanoribbons and nanorings is demonstrated. Aromatic self-assembled monolayers are locally cross-linked by electron beam lithography into polymeric carbon nanosheets. Annealing at 1200K in ultrahigh vacuum transforms these electrically insulating nanosheets into a conducting two-dimensional phase consisting of nanopatches of graphene with a sheet conductivity of ∼10−2Ssq. The method allows the direct writing of patterns into the monolayer, permitting the resistless fabrication of arbitrarily sized and shaped carbon nanostructures with a thickness of 1nm.
