The CVD approach to producing graphene (Fig. 1) relies on dissolving carbon into the nickel substrate, and then forcing it to precipitate out by cooling the nickel. The thickness and crystalline ...

Graphene-based saturable absorbers show strong potential for high-speed laser systems. Learn how integrating graphene with silicon photonics improves mode-locking and ultrafast pulse generation.

Another method with some promise is “chemical vapour deposition” (CVD). This involves reacting methane, which is rich in carbon, with copper to leave sheets of graphene. But this is not ideal ...

In electronic applications, the major bottleneck is the requirement of large size samples, which is possible only in the case of CVD process, but it is difficult to produce high quality and single ...
