Energy band engineering via “Bite” defect located on N = 8 armchair graphene nanoribbons

Length-dependent symmetry in narrow chevron-like graphene nanoribbons

“… 26 Our results are in excellent agreement with those in ref. 26 . It is clear from these results that the electronic properties of such a ribbon are vastly altered, with an upshift of the HOMO by ∼0.5 eV and an upshift of the LUMO of ∼0.2 eV and a corresponding band gap decrease, with respect to the pristine ones without a junction.…”

In silico design of graphene plasmonic hot-spots

“…In particular, we focus on systems that can be experimentally obtained, e.g. bite defects arising in graphene nanoribbons (GNRs) [46][47][48][49][50] or cracks propagating in polycrystalline graphene (PCG) under the effect of mechanical strain. [51][52][53] Therefore, we showcase the pivotal role of atomically dened defects in increasing enhancement and eld connement in graphene-based nanostructures.…”
