چکیده انگلیسی
Several straight hetero-junctions carbon nanotubes (CNTs) are constructed and their tensile behavior are investigated. It is pointed that the Young's modulus of hetero-junctions is lower than the values of their fundamental homogeneous CNTs due to the existence of pentagon-heptagon pair defects. In addition, it is revealed that the Young's modulus of homogeneous zigzag CNTs increases by increasing the chiral number of these nano-structures. Finally, it is concluded that as the connecting length of the hetero-junctions increases the Young's modulus of these particular CNTs decreases. Therefore, the tensile strength of hetero-junctions depends on the presence of pentagon-heptagon pair defects.
