Since its discovery, graphene has attracted much attention due to its unique elec. transport properties that can be applied to high-performance field-effect transistors (FETs). However, mounting chem. functionalities onto graphene inevitably involves the breaking of sp2 bonds, resulting in the degradation of the mech. and elec. properties compared to pristine graphene. Here, we report a new strategy to chem. functionalize graphene for use in FETs without affecting the elec. performance. The key idea is to control the Fermi level of the graphene using the consecutive treatment of gold nanoparticles (AuNPs) and thiol-SAM (self-assembled monolayer) mols., inducing pos. and neg. doping effects, resp., by flipping the elec. dipoles between AuNPs and SAMs. Based on this method, we demonstrate a Dirac voltage switcher on a graphene FET using heavy metal ions on functionalized graphene, where the carboxyl functional groups of the mediating SAMs efficiently form complexes with the metal ions and, as a result, the Dirac voltage can be pos. shifted by different charge doping on graphene. We believe that the nanoparticle-mediated SAM functionalization of graphene can pave the way to developing high-performance chem., environmental, and biol. sensors that fully utilize the pristine properties of graphene. The experimental process involved the reaction of 3-Acetyldihydrofuran-2(3H)-one(cas: 517-23-7).SDS of cas: 517-23-7
