Fine band gap modulation effects of aGNRs by an organic functional group: a first-principles study

Fine band gap modulation effects of aGNRs by an organic functional group: a first-principles study

We report a first-principles study of the electronic structure of functionalized graphene nano-ribbon (aGNRs-f) by organic functional group (CH2C6H5) and find that CH2C6H5 functionalized group does not produce any electronic states in the gap and the band gap is direct. By changing both the density of the organic functional group …
