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 (n,0) zigzag single-walled BCN alloy nanotube in the CNT/BCN/CNT structure, where nanocontacts are considered as (n,0) zigzag single-walled carbon nanotubes. Our calculations show that the conductance is sensitive to the n index. With I–V characteristics, this system can be a possible candidate for a nanoelectronic switching device.
