New research shows that graphene can be chemically doped using nitrogen atoms - which suggests that graphene electronics can use processes used in silicon based technology. The research also confirmed that you can use other elements (such as Boron) to complementary dope graphene.
As is the case in Silicon, the extra nitrogen atoms do not significantly modify the basic structure of graphene sheets.
The research team (from the US and Korea) say that nitrogen-doped graphene may be more chemically reactive then non-doped graphene - and could potentially be used in applications like chemical sensors, transistors and other electronics devices.
