Abstract

The electronic structure, band gap and density of states of (7,7) Armchair carbon nanotube by the full potentiallin- earized augmented plane wave (FP-LAPW)method in the framework density functional theory (DFT) with the generalized gradient approximation (GGA) were studied. The calculated band structure and density of state of Armchair (7,7) carbon nanotube were in good agreement with theoretical and experimental results.
