Spin-resolved band structures and transport properties of δ-graphyne nanoribbon with bilateral or unilateral fluorination

Abstract

Among the graphyne family, δ-Graphyne is a new typical representative for instance. In this article, we have studied the spin-splitting phenomena in the band structures and transport properties of zigzag δ-graphyne nanoribbron (ZδGYNR) with edge fluorination. Our results show that the spin-splitting can be observed obviously in the ZδGYNRs with unilateral or bilateral edge fluorinations. Moreover, some distinct physical effects, such as spin-filtering, rectification and negative differential resistance, can be found in the proposed device models. Particularly, the efficiency of spin-filtering can approach to 100% in the antiparallel spin-configuration of the bilateral fluorination model, which would be capable of leading to promising applications in spintronics and nanodevices.
