Control of the electronic properties of graphene by hydrogenation. Graphene is not only the thinnest form of carbon in existence, it's the strongest. ELEMENTARY ELECTRONIC PROPERTIES OF GRAPHENE A. Interest in graphene isn't limited to its fundamental properties. The material is also a candidate for replacing silicon as a basis of faster, more powerful electronics. Abstract. Owing to its unusual electronic spectrum, graphene has led to the emergence of a new paradigm of 'relativistic' condensed-matter physics, where quantum relativistic phenomena can now be mimicked and tested in table-top experiments. That was until it was isolated in 2004 by two researchers at The University of Manchester, Professor Andre Geim and Professor Kostya Novoselov. In October 2004, Geim published a paper announcing the achievement of graphene sheets in Science magazine, entitled "Electric field effect in atomically thin carbon films.". Graphene is the two-dimensional building block for carbon allotropes of every other dimensionality. Here, graphene oxide (GO) was prepared by oxidizing the purified natural flake graphite (NFG) by a modified Hummers method. These factors allow for true multi- and cross-disciplinary research. 1.Graphene films.
