Carbon-based nanomaterials are good candidates to be used in the development of electronic circuitry using the bottom-up approach, because they havesemiconductor properties and dimensions within the required physical limit to construct electrical connections. Forexample, the unique electronic properties of fullerenes have made the construction of molecular rectifiers and molecular transistors that can work with more than two logical states. Carbon nanotubes have shown their values to be used in the construction of molecular wires and FET transistors thatcan operate in the THz frequency bias range. On the other hand, graphene is not only themost promising material for replacing ITO in the construction of transparent electrodesbut it has also shown quantum Hall effect and quantum conductance properties that depend upon the edges or chemical doping. The purpose of this work is to present recentdevelopmen...
