Future applications of graphene rely highly on the production of large‐area high‐quality graphene, especially large single‐crystalline graphene, due to the reduction of defects caused by grain boundaries. However, current large single‐crystalline graphene growing methodologies are suffering from low growth rate and as a result, industrial graphene production is always confronted by high energy consumption,...
In article 1702916, Hailin Peng, Zhongfan Liu, and co‐workers demonstrate low‐temperature, rapid growth of graphene using ethane as a carbon feedstock. The authors achieve both a higher growth rate and larger domain size in comparison to the methane method. This study brings new insights into the effect of carbon feedstock on graphene growth, reducing the energy consumption for massive synthesis of...
A second passivation and a multistage carbon‐source supply (CSS) allow a 50‐fold enhancement of the growth rate of large single‐crystalline graphene with a record growth rate of 101 μm min−1, almost 10 times higher than for pure copper. To this end the CSS is tailored at separate stages of graphene growth on copper foil, combined with an effective suppression of new spontaneous nucleation via second...
