Compared to the two-dimensional graphene whose band gap remains close\nto zero even if a large strain is applied, the band gap of graphene nanoribbon\n(GNR) is sensitive to both uniaxial and shears strains. The effect of strain on\nthe electronic structure of a GNR strongly depends on its...

delocalized electronic properties significantly. As shown inFig. 5b, the calculated band structure of the graphene-like nanoribbon has a direct gap of 0.6 eV, which is underestimated in comparison to our experimental result (1.38 eV). It has been reported that the Heyd–Scuseria–Ernzerhof...
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-...
Implications of the edge states for the band structure of armchair graphene nanoribbons doi:10.1007/s42823-024-00824-zThe one-electron states of (7,38) armchair graphene nanoribbon (AGNR) have been investigated in the ground and excited singlet electronic states by a multi-configuration ensemble ...

Graphenenanosheet (GNS), armchair graphenenanoribbon (AGNR), and zigzag graphenenanoribbon (ZGNR) systems were investigated by first principle calculations using the density functional theory (DFT). The DFT calculations explored the potential of utilization of these materials as gas sensors to detect ...

As it can be seen, the more particle moves toward the nanoribbon, the more significant force it feels. Fx has two peaks when the nanoparticle reaches two sides of the graphene nanoribbon; meanwhile, at the center of the ribbon, Fx is zero due to the symmetry of the structure. When the ...
