ABSTRACT
Different molecular wires, nanodevices, and simple nano-ICs have been devised and tested. Nanostructures and devices should be examined studying underlying atomic structures. Carbon nanotubes, fullerenes, and other carbon structures have a valence band generated by valence electrons. Carbon nanotubes can be visualized as sheets of graphite rolled into hollow (but closed-ended) cylinders. Carbon nanotubes can be widely used in MEMS and NEMS, as well as in nanoelectronics. Carbon nanotubes exhibit metallic, semimetallic, and semiconducting properties depending on chirality and diameter. By making use of distinct classification methods, including the decision trees, the carbon nanotubes were classified. Carbon nanotubes can be visualized as sheets of graphite rolled into hollow (but closed-ended) cylinders. The carbon nanotubes, which are stronger than steel wire, can be added to the media to make the conductive composite materials as well as to change its mechanical properties. The chapter discusses carbon-based nanoelectronics, in particular, fullerene-centered nanoelectronics and biocentered nanoelectronics.
