Abstract
Graphene-based hybrid thin films are investigated specifically for its optical transmittance and sheet resistance. The hybrid films were made of stacked or fused chemical vapor deposition (CVD)-grown graphene, carbon nanotubes (CNT) and copper nanowires. It was found that the fused graphene/CNT has the highest transmittance nearly 90% in the visible region and the lowest sheet resistance (RS) of similar to 830 Omega/square. Upon further optimization, it is believed that the latter parameters can be significantly improved and made it feasible to be used as transparent conductive electrode (TCE) for optoelectronic devices.
