| 제목 | Effect of terminal groups in amine-based organic compounds on work-function decrease of graphene |
| 초록 | We have demonstrated that amine and alkyl groups, applied by a simple spin-coating method, can provide an n-type doping effect on graphene sheets. The organic compounds used in this work are based on amine, phenyl amine, butylphenyl amine, benzoylphenyl amine, and tolylvinylphenyl amine groups. In particular, graphene doped with butylphenyl amine showed the strongest n-type effect among all the samples because butylphenyl amine had the strongest binding energy with graphene sheet and dispersion property in a nonpolar solvent. The effect of terminal groups in phenyl amine organic compounds on work-function decrease of graphene is also investigated. These results suggest that amine and alkyl groups play a crucial role for n-type doping of graphene.
