One-dimensional carbon nanotubes (CNTs) show metallic and semiconducting properties depending on the chirality and diameter, while two-dimensional graphene reveals only metallic properties.Although numerous applications have been demonstrated with CNTs due to their versatile properties, the applications to field effect transistors have been often hindered by the metallic properties.On the other hand, graphene have been used for quantum mechanical tunneling devices, while graphene as layered electrodes have been extensively studied.In this talk, I will focus on the graphene grain boundary to correlate with sheet resistance.Issues, recent advances,bottleneck technologies, together advantages and drawbacks of these two materials for switching devices will be extensively discussed.I will also demonstrate several examples of synergistic effect of CNT-graphene hybridizedstructures.The possibility of realizing transparent, flexible and stretchable devices using all carbon materials will be also discussed.
