First-principles calculation of optical conductivity response in armchair graphene nanoribbon

2D materials is of great interest for making future high pase electronic devices. In this talk, I will present first-principles calculation results for conductivity measurements in pristine 7 zigzag edge of armchair graphene nanoribbons (7aGNRs), periodicity crystal structures of single boron doped 7aGNRs and periodicity crystal structures of ring-pentagon 7aGNRs. I will report that pristine unstrained 7aGNRs is optically inactive but turns to be optically active due to the application of strain engineering. In boron doped and ring-pentagon structures of 7aGNRs, first-priciples calculation results show non-vansihing optical conductivity because doping with boron atom and creating a single carbon atom vacancy convert graphene into mettalic. I will also present the response of strain on the Berry curvature of these structures. Result suggests that fermions are spread through out the Brillion zone in the reciprocal space for optimized 7aGNRs but localized near the Γ-point due to application of strain.
