摘要：

The layer numbers of graphene for graphene based transparent conductive films are crucial. An appropriate number of graphene layers would provide excellent electrical conductivity along with high transparency. Herein, we demonstrated a facile and scalable technique to grow graphene with controllable layers on copper foil substrates using the etching effect of H-2 in atmospheric pressure chemical vapor deposition (APCVD), and studied the influence of H-2 etching on the properties of graphene transparent conductive films. The etching of formed multi-layer graphene (MLG, 12-14 layers) for Cu substrates assists the formation of few-layer graphene (FLG, 2-3 layers). These as-obtained graphene can be used as high performance transparent conductors, which show improved tradeoff between conductivity and transparency: the transmittance of 96.4% at 550 nm with sheet resistance of similar to 360 Omega sq(-1), and the transmittance of 86.7% at 550 nm with sheet resistance of similar to 142 Omega sq(-1). They could be used as high performance transparent conductors in the future.
