Supracrystalline nanoribbons for nanoelectronics

In the last two decades various forms of carbon nanostructures have attracted a great deal of interest due to their novel fundamental properties and possible applications in electronics. With the developments in production methods, these materials have emerged as one of the most promising materials for non-silicon electronics. Among carbon nanostructures graphene is a flat monolayer of carbon atoms tightly packed into a 2-D honeycomb lattice and is considered as the basic building block of other graphitic materials in all dimensions [1]. In the past, 2-D materials were thought to be thermodynamically unstable and could not exist. In 2004, experimental discovery of graphene showed that these materials can exist in liquid suspensions or on non- crystalline substrates. Because of this fact, theoretical studies on graphite are much more than experimental ones. The possibility of more complicated than graphene two-dimensional periodic structures existence has been theoretically proved. There are not separate atoms or ions but its symmetric complexes at the nodes at their crystalline lattice [2]. They were called as supracrystals.
