The aim of the paper is to study the ballistic quantum transport in armchair graphene nanoribbon by developing a transport model followed by subsequent simulation. Electron transport in nanodevices can be studied by two different methods viz. wave function method and non-equilibrium Green function ...

At the same time, roughness at the edges washes out chiral signatures, making the nanoribbon width the principal arbiter of metallicity. The width-dependent conductivity allows the design of a monolithically patterned wide-narrow-wide all graphene interconnect-channel heterostructure. In a three-...

Nanoribbon-like PAHs were reported by Yang et al.,13 which showed graphene-like properties in the form of graphene nanoribbons (GNRs). If such GNRs can be extended in size, PAHs can be a new approach for graphene synthesis by total organic synthesis route. Other GNRs was reported on gold ...
The band energy of graphene nanoribbon is parabolic when reaching the minimum band energy. Otherwise, it is nonparabolic. In the parabolic band structure, Fermi-Dirac integrals are employed to study the carrier statistic whereas for nonparabolic part, numerical solutions are needed. Numerical method ...
Lattice structures of edge-extended AGNRs for (a) 7/9-AGNR nanoribbon, (b) staggered edge-extended AGNR, and (c) inline edge-extended AGNR. The grey hexagons denote pristine AGNRs while the red hexagons represent the edge-extended areas. The green and blue dashed rectangles indicate the...

nanoribbon, as expected, the lowest average energy corresponds to the unstrained state and the larger contract (elongate) deformation corresponds to the higher average energy. At a certain strain, the average energy increases with decreasing the ribbon width n. The average energy increases quadraticall...
