Carbononics is a new field that is all about creating new materials using basic carbon atoms. Graphene is the most basic 2D carbon material - a single sheet of carbon atoms (graphene is the world's strongest and most conductive material).
Graphene can be cut to tiny flakes - if these are nano-sized, they are called Quantum Dots (QDs), and these nanoparticles have interesting properties. By controlling the size, shape, edge, symmetry and other properties of those graphene quantum dots (QGDs), one can create all sorts of devices - which integrate electronics, photonics and spintronics operations. The ultimate goal of carbononics is to create a graphene-based quantum circuit.
Carbononics is still in a very early stage, but it may become a promising field of study and commercialization in the future.
