Carbon nanotubes (CNTs) are quasi-one-dimensional nanostructures with unique electrical properties that make them ideal candidates for applications in nanoelectronics. Since the discovery of carbon nanotubes (CNTs) just over a decade ago [1], their unique electronic and structural properties have aroused great excitement in the scientific community and promise a broad range of applications. A wide variety of nanotube-based electronic devices, such as diodes, transistors, or field emitters [2-4], has been already theoretically modeled and experimentally achieved. The studies show that the CNT can be metallic or semiconducting depending on diameter and chirality [5, 6]. By joining two perfect CNTs one can form a superlattice by introducing pentagon–heptagon pairs at the interface [5]. Following this idea, a number of CNT superlattices [7, 8], junctions [9], and nanodevices [10] have thus been obtained
