New Generation of Carbon Nanotubes: Graphdiyne Nanotubes

We present a theoretical study of the electronic and optical properties of graphdiyne-basednanotubes (GDNT). These semiconducting nanotubes result from the elongation of one-thirdof the covalent interconnections of graphite-based nanotubes by the introduction of ynegroups. In the present investigation, the electronic, structural and optical properties ofGDNTs having different diameters have been studied systematically
