我们展示了一种创造独特形式的纯sp(2)键合碳和前所未有的杂多分子的技术。这些新的结构，我们称之为雕塑，是通过从双层石墨烯、异质双层或多层材料中雕刻选定的形状并允许这些形状自发重建而形成的。最简单的雕刻烯在拓扑上相当于一个环面，其尺寸相当于富勒烯的尺寸。这些新分子结构的拓扑结构是稳定的，不受原子尺度缺陷的影响。我们证明，雕塑可以形成中空、多连接结构的基本构件，具有潜在的纳米流体和纳米电子学应用。
We demonstrate a technique for creating unique forms of pure sp(2)-bonded carbon and unprecedented heteromolecules. These new structures, which we refer to as sculpturenes, are formed by sculpting selected shapes from bilayer graphene, heterobilayers, or multilayered materials and allowing the shapes to spontaneously reconstruct. The simplest sculpturene is topologically equivalent to a torus, with dimensions comparable to those of fullerenes. The topology of these new molecular structures is stable against atomic-scale defects. We demonstrate that sculpturenes can form the basic building blocks of hollow, multiconnected structures, with potential applications to nanofluidics and nanoelectronics.
