Abstract
- The symmetry and electronic properties of armchair graphene nanoribbons (AGNRs) have been investigated using density functional theory calculations. For the shear strained AGNRs, the D6h (6/mmm) symmetry of the hexagonal lattice further turns into 2/m. The stability improves with increasing ribbon width under the same shear strain. Besides, the modification of the energy gap under shear strain is weak.
