Graphene/g-C3N4 bilayer

[rupesh_shukla]

1) is graphitic carbon nitride (g-C3N4) available ?? because i have searched and could not find from database...
2) can we just make a graphene bi-layer using graphite.. and in the 2nd layer replace the carbon atom alternatively with nitrogen to make carbon nitride

Starting out from graphite or graphene sounds like a reasonable approach, provided that you optimize the geometry afterwards.
