Spin Effect on Band Structure of Zigzag and Armchair Graphene Nanoribbones with Stone-Wales defect

In this paper the band structure of spin polarized zigzag graphene nanoribbons(ZGNRs) and armchair graphene nanoribons(AGNRs) with Stone-Wales defect are investigatedThe results show when the spin effect is considered the band structures of ZGNRs and AGNRs will be changed and modifiedA larger gap will be created and the degenerate bands in ZGNRs will become far from each other.tight-binding and hubard model were used to simulate the band structures.
