石墨烯纳米折纸的扫描隧道显微镜研究

Graphene nano-origami using Scanning Tunneling Microscopy

Kim Akius, Jan van Ruitenbeek

摘要:

先前已经使用基于原子力显微镜(AFM)和扫描隧道显微镜(STM)的技术两者示出了在高度取向的热解石墨(HOPG)上的石墨烯纳米图案化,所述基于原子力显微镜(AFM)和扫描隧道显微镜(STM)的技术包括内在台阶边缘的折叠和石墨烯层中的电化学蚀刻或切割。在这里,我们报告了一种新技术的发展,结合电化学蚀刻和折叠使用机械STM操纵。我们的技术显示了前所未有的控制纳米级的石墨烯折叠在多个折叠步骤,并可能是一个路线的STM研究魔角石墨烯与原位制造的样品。

英文摘要:

Graphene nanopatterning on highly oriented pyrolytic graphite (HOPG) has previously been shown using both atomic force microscopy (AFM) and scanning tunneling microscopy (STM) based techniques, including folding of intrinsic step edges and electrochemical etching or cutting in graphene layers. We here report development of a new technique, combining electrochemical etching and folding using mechanical STM manipulation. Our technique shows unprecedented control of nanoscale folding of graphene in multiple folding steps and could be a route towards STM study of magic angle graphene with in-situ fabricated samples.
