A 2D material (although argued recently), one of the layers of the graphite solid, graphene was isolated a few years ago by Novoselov et. al and proven useful for its electrical properties.
In the rise of graphene, Novoselov group (graphene.org) reviews advances and things that we can do with or without graphene indicating "unusual electronic spectrum" graphene presents.
