Dual doping-driven perpendicular electric field with opposite directions remarkably increase the on/off current ratio of bilayer graphene field-effect transistors. This unambiguously proves that it is possible to open a bandgap two molecular dopants (F4-TCNQ and NH2-functionalized self-assembled monolayers (SAMs)) even in single-gate device structure.
