Evaluating graphene nanoribbons for miniaturization of field effect transistors: a density functional theory study

HIGHLIGHTS

• What: The authors propose a novel method to successfully increase the band gap of 7-armchair nanoribbons by introducing the pre-designed shape of cutting. The focus of the research is thus twofold: firstly, to open a band gap in graphene, and secondly, to manipulate the band structure by precisely cutting the edges of the graphene nanoribbons. For that reason, the objective of this research is to evaluate and parameterize electronic properties presented in a range of shapes of GNRs, using density functional theory (DFT). The authors first compare the results of the band structure of graphene . . .
