On the charge transfer between single-walled carbon nanotubes and graphene

Journal Article

Abstract

​It is important to understand the electronic interaction between single-walled carbon nanotubes(SWNTs) and graphene in order to use them efficiently in multifunctional hybrid devices. Here, we deposited SWNT bundles on graphene-covered copper and SiO2 substrates by chemical vapor deposition and investigated the charge transfer between them by Raman spectroscopy. Our results revealed that, on both copper and SiO2 substrates, graphene donates electrons to the SWNTs,resulting in p-type doped graphene and n-type doped SWNTs.
