The application relates to a strongly-polarized molecule of the following general formula: wherein A denotes a group having a polarizability greater than 2 C·m 2 /V; R 1 and R 2 are respectively hydrogen, halogen, a hydroxyl group, an amino group, a cyano group, a nitro group, a carboxyl group, a C 1-12 alkyl group, a C 1-12 alkoxy group, a halogenated C 1-12 alkyl group, a halogenated C 1-12 alkoxy group, a hydroxyl C 1-12 alkyl group, a hydroxyl C 1-12 alkoxy group, or a C 1-12 alkyl amino group; x 1 and x 2 denote 0 or an integer no less than 1, respectively; and y 1 and y 2 denote 0 or an integer no less than 1, respectively. The application further relates to a strongly-polarized molecule-graphene molecule heterojunction, and a single molecule field effect transistor comprising a substrate, a gate, a dielectric layer and the strongly-polarized molecule-graphene molecule heterojunction; and the dielectric layer is located between the gate and the strongly-polarized molecule-graphene molecule heterojuction. The single molecule field effect transistor provided by the application can realize highly-efficient gate modulation. |
