摘要: Hexagonal boron nitride sheet has been shown to be the best insulating substrate for graphene electronics. Using first-principles calculations, we here show that BN nanoribbons (BNNRs) can not only serve as a desirable but also bring new properties into supported (GNRs). In particular, zigzag GNRs on BNNRs become spin-relevant semiconductor easily tuned half-metal, thanks polar character of BNNRs. contrast, armchair basically have all their electronic survived from interaction Our findings provide helpful guide developing hybrid BN-graphene nanodevices.
