Controllable doping of graphene via inverse transfer method for organic electronics |
| 초록 |
Graphene growth by chemical vapor deposition and following wet transfer process using polymer supporting layer are useful method to produce large area and high quality graphene on target substrate. We report a simultaneous wet transfer and doping method using hydrophobic polymers with various functional groups. The inverse transfer method was introduced to make graphene/polymer structure on target substrate, which leaves the polymer supporting layer between substrate and graphene as a dopant without leaving any involuntary polymer residues on top of graphene. The doping effect was confirmed by using Raman spectroscopy and ultraviolet photoelectron spectroscopy. Moreover, we also applied this method to demonstrate organic field-effect transistors with graphene electrodes. Considering flexibility and tunability of polymers, this method would provide valuable directions for graphene-based soft electronics. |
