n this paper, electronic properties of single-wall armchair and zigzag carbon nanotubes (CNTs) superlattices, n(12,0)/m(6,6) and n(12,0)/m(11,0) are investigated. For this reason, the topological defects of pentagon–heptagon pairs at interfaces of carbon hexagonal network appear. These defects break the symmetry of the system, and then change the electrical properties. The calculations include two parts: investigation of the structures in the absence and presence of the impurity effect, which are calculated by the nearest-neighbor tight binding model . Out numerical results can be useful in designing nanoelectronic devices based on carbon nanotubes.
