Abstract

The mobility of graphene transferred on a SiO₂/Si substrate is limited to ∼10 000 cm²V^-1s^-1. Without understanding the graphene/SiO₂ interaction, it is difficult to improve the electrical transport properties. Although surface structures on SiO₂ such as silanol and siloxane groups are recognized, the relation between the surface treatment of SiO₂ and graphene characteristics has not yet been elucidated. This paper discusses the electrical transport properties of graphene on specific surface structures of SiO₂ prepared by O₂-plasma treatments and reoxidization.
