Figure 4From: Quantum transport simulations of graphene nanoribbon devices using Dirac equation calibrated with tight-binding π-bond modelThe DOS ( E ) and T ( E ) of (a) W12 and (b) W14 devices with the best-fit l 0 (from E(k) calculations) at U = 0 agreeing to that of the TB- π model. Both the DOS(E) and T(E) are symmetric about E = 0.Back to article page
