Single Crystalline Graphene-based Transparent Electrode with Extremely High Folding Resistance |
| 초록 |
Graphene is a promising substitute of current transparent conducting materials due to its outstanding physical properties. However, polycrystalline graphene (PCG) with numerical structural defects is generally used for the transparent electrode studies. Single crystalline graphene (SCG) has never been used as transparent electrode because it has been a great challenge to synthesize it with large size and some simulation studies show that electrical and mechanical properties would be the same with PCG with large grain size. Here we demonstrate transparent flexible electrode using SCG and compared its properties with PCG. We have confirmed SCG has much improved mechanical and barrier properties and especially the sheet resistance of SCG-based electrode maintained during 10000 times of folding test with 0.5 mm of folding radius. This result shows better macroscopic properties of SCG and its advantages for applying electronic devices. |
