Outline of Final Research Achievements

Synthesis of vertically standing graphene from single-walled carbon nanotube (SWNTs) is realized through the adjustment of ion energy coming to the substrate during plasma CVD. The detailed electrical measurements reveal that the vertically standing graphene on SWNTs acts as a quantum dot for the carrier transport of SWNTs with high thermal stability. Decoration of nanoparticles on the vertically standing graphene is also realized aiming for the molecular motor application. Clear plasmonic response can also be observed from the nanoparticles decorated on the vertically standing graphene. Since the novel hybrid nanomaterial, nanoparticle decorated-vertically standing graphene/SWNTs, includes optically responsible and room temperature stable quantum dot structure, this novel material can be useful for wide variety of optoelectrical applications.
