▎ 摘 要
A high performance, highly stable transparent conducting structure based on microscale copper/nickel grids wrapped with graphene is presented. Graphene is selectively deposited on the surfaces of the microgrids by atmospheric pressure chemical vapor deposition method. The optical transmittance of the copper/nickel microgrid sample is similar to 80% over the visible and near-infrared spectra with a very small sheet resistance of similar to 0.58 Omega/sq. After the high temperature deposition of graphene, the sample's transmittance increases to be similar to 90% due to the line width reduction of the microgrids while the sheet resistance also increases to similar to 5 Omega/sq. The graphene layer is deposited to keep the copper/nickel surfaces from being oxidized in the air. Both stability testing and composition spectra results confirm the long-term stability of the copper/nickel microgrids wrapped with graphene. (C) 2014 AIP Publishing LLC.
