石墨烯通常被认为是未来纳米电子学最有前途的候选者之一。作为石墨烯基电子产品中不可或缺的组成部分，与其他材料形成结不仅提供了实用功能和可靠的连接，而且还可以改善或改变原始石墨烯的性质，为新的应用开辟了可能性。在这里，我们展示了由单壁碳纳米管的可控解链产生的分子内结，其在一维纳米结构中结合了石墨烯纳米颗粒和单壁碳纳米管。该结显示出强的栅极依赖整流行为。作为应用，我们展示了在原型方向依赖场效应晶体管，逻辑门和高性能光电探测器中使用的结，表明其在未来石墨烯基电子和光电子学中的潜力。
Graphene is often regarded as one of the most promising candidates for future nanoelectronics. As an indispensable component in graphene-based electronics, the formation of junctions with other materials not only provides utility functions and reliable connexions, but can also improve or alter the properties of pristine graphene, opening up possibilities for new applications. Here we demonstrate an intramolecular junction produced by the controllable unzipping of single-walled carbon nanotubes, which combines a graphene nanoribbon and single-walled carbon nanotube in a one-dimensional nanostructure. This junction shows a strong gate-dependent rectifying behaviour. As applications, we demonstrate the use of the junction in prototype directionally dependent field-effect transistors, logic gates and high-performance photodetectors, indicating its potential in future graphene-based electronics and optoelectronics.
