Researchers from Rice University and the Hong Kong Polytechnic University discovered that Graphene nanoribbons could stand tall on substrates and also form arcs. The contact between the graphene and substrate (which could be diamond and also nickel) is very light and so the graphene retains nearly all of its inherent electrical or magnetic properties. Using such a design can theoretically enable putting 100 trillion graphene-wall field-effect transistors (FETs) on a square-centimeter chip.
