The CNT/BCN/CNT structure (zigzag type) as a molecular switch

Using a tight-binding model and some well-known approaches and methods based on Green's function theory and Landauer formalism, we numerically investigate the conductance properties and I-V characteristics of zigzag single-walled BCN alloy nanotube in the CNT/BCN/CNT structure, where nanocontacts are considered as zigzag single-walled carbon nanotubes. Our calculations show that any increasing in considerably give rise to the enhancing of the conductance of the system. With our system characteristics, this system can be a possible candidate for a nanoelectronic switching device.
