Figure 3From: Analytical performance of 3 m and 3 m + 1 armchair graphene nanoribbons under uniaxial strainThe plot of ribbons' width versus the energy bandgap for two different families. (a) n =3 m and (b) n =3 m +1. The comparison with the calculation based on density functional theory by Khaliji et al. [18] shows excellent agreement.Back to article page
