We review the principles of formation, physical properties, and current or envisaged
applications for a wide range of carbon allotropic forms. We discuss experimental and …

Abstract Fifty years ago Walter Kohn speculated that a zero-gap semiconductor might be
unstable against the spontaneous generation of excitons–electron–hole pairs bound …

Single-wall carbon nanotubes provide ideal model one-dimensional (1-D) condensed
matter systems in which to address fundamental questions in many-body physics, while, at …

We have investigated the electronic and optical properties of ultra-small (3, 3),(4, 4) and (5,
5) armchair single walled nanotubes carbon (C-SWNTs) and boron nitride (BN-SWNTs) …

The structural and electronic properties of (3, 3) ultra-small SWCNT doped with nitrogen at
different sites namely N (3, 3) _ 1, N (3, 3) _ 2 and N (3, 3) _ 3 are investigated by DFT …

This article establishes a link between the structural form of a polymer and its light
absorption properties using density functional theory. According to a relationship …

We report a detailed comparison of ultraclean suspended and on-substrate carbon
nanotubes (CNTs) in order to quantify the effect of the substrate interaction on the effective …

Armchair and zigzag edge terminations in planar hexagonal and trigonal graphene
nanorings are shown to underlie one-dimensional topological states associated with …

Single walled carbon nanotubes (SWCNT) are attractive materials for thermoelectric (TE)
devices because of their unique one-dimensional structure and provide us for develo** a …

In the present work, we consider the electronic properties of graphene with Kekule structure
formed from two different C–C bonds in its hexagonal lattice. When the C–C bond …
