Graphene: Self‐Aligned Single‐Crystal Graphene Grains (Adv. Funct. Mater. 12/2014)

Self-aligned graphene grains are precisely controlled on liquid Cu by G. Yu and co-workers, using ambient pressure chemical vapor deposition. Large-scale monolayer graphene arrays are modulated by varying the growth conditions such as the flow rate of the carbon source, growth temperature, and growth time. On page 1664, the as-grown graphene arrays show reasonable mobility and high current density, showing great potential for graphene-based electronics.
