The mobility of graphene transferred on a SiO2/Si substrate is limited to similar to 10 000 cm(2)V(-1)s(-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 O-2-plasma treatments and reoxidization.
