بررسي اثرات ناخالصي كبالت (Co) بر خواص الكتريكي نانو لوله ي كربني آرمچير (6 و 6)

The investigation of the impurity Co effect on the electronic properties of the Armchair

In this study the electronic structure properties of armchair single-walled carbon nanotubes (6,6) have been investigated with the help of density functional theory. Studies using the full-potential linearzed augmented plane wave method within density functional theory Hvhnbrg, Kohn and Sham generalized gradient approximation by the code Wien2K done. With the addition of cobalt magnetic impurities within carbon nanotubes, the effect of cobalt on the electrical properties of the nanotubes is investigated.The results of this study are in good agreement with experimental and theoretical results of others
