제목 Electrical Properties of Graphene Field-Effect Transistors Depending on Doping Location and Dual Doping
초록   Graphene field-effect transistors can be doped by p-type or n-type molecular doping materials. Molecular doping materials improved electrical properties of graphene field-effect transistors. We studied that different location of n-doping on graphene resulted different doping effect. And this effect influenced the device performance. In addition, dual doping where the molecular doping materials are located both on and under the graphene active layer was studied. Moreover, we observed that the molecular n-type doping materials was unstable. So it can lose its n-type doping ability and even serve as p-type doping materials under specific conditions. Our results provide insights into the strategies to selectively adjust and improve the performance of graphene field-effect transistors utilizing the molecular doping concept.
