  In this paper, the uniaxial strain effect on the electronic properties of (6,6) finite armchair carbon nanotube was investigated by using the Green function technique and Landure-Buttiker formula. It was found that, in (6,6) finite carbon nanotube with 3q and 3q+1 length, where q is a certain integer, the current was induced by the application of a suitable tensile strain and compressive strain in low voltage, respectively. The current of (6,6) finite carbon nanotube with 3q-1 length was decreased by loading the uniaxial strain. According to the results semiconductor-metal transition in (6,6) finite carbon nanotube and vice versa is observed by applying uniaxial strain.
