Nanoenvelopes: Wrapping a Single-Walled Carbon Nanotube with Graphene using an Atomic Force Microscope.

Abstract

Engineering the morphology and structure of low-dimensional carbon nanomaterials is important to study their mechanical and electrical properties and even superconductivity. Herein, first the techniques that are used to engineer carbon nanotubes, including manipulation, morphology modification, and fabrication of complex nanostructures, are reviewed. This is followed by a summary of the methods applied to fabricate graphene nanostructures, such as heterostructures and nanoenvelopes of graphene. Lastly, an insight into the applications of low-dimensional-carbon-based electronics is given, such as carbon nanotube (CNT) transistors, graphene-based nanoenvelopes, and graphene-contacted CNT field-effect transistors (FETs), which are promising components in future electronics.
