Intrinsic doping and gate hysteresis in graphene field effect devices fabricated on SiO2 substrates.
We have studied the intrinsic doping level and gate hysteresis of graphene-based field effect transistors (FETs) fabricated over Si/SiO(2) substrates. It was found that the high p-doping level ofExpand
