Single wall carbon nanotubes have been identified as molecular quantum wire with good conductance over micron length scales. Nanotube heterojunctions provide rectifying switching characteristics and room-temperature field effect nanotube transistor on a SiO 2 surface has been recently demonstrated. The structural stability and electronic characteristics of such junctions are studied to investigate the possibility of, easy to fabricate, nanotube hetero-junctions and devices. N or P character to the nanotube is imparted.
Studies show that sharp carbon-heteroatomic nanotube interfaces are also possible.
BN nanotubes show BN bond rotation and BB, NN bond frustration effects which limit the type of topological defects that are allowed in a BN hexagonal network. BN tube tips are non-fullerene type flat, conical, or amorphous nature that is related with the chirality of the BN nanotube considered. Quantum dynamic simulations show that heteroatomic nanotubes deform significantly different than the carbon nanotubes. The possible applications of such deformations in nano-mechanical devices will be discussed. Overall, the studies indicate that a much wider spectrum of molecular electronic and mechanical system components are possible than the previously proposed only carbon nanotube based nanosystem components.
