Title: Spin transport properties of partially edge-hydrogenated MoS{sub 2} nanoribbon heterostructure

We report ab initio calculations of electronic transport properties of heterostructure based on MoS{sub 2} nanoribbons. The heterostructure consists of edge hydrogen-passivated and non-passivated zigzag MoS{sub 2} nanoribbons (ZMoS{sub 2}NR-H/ZMoS{sub 2}NR). Our calculations show that the heterostructure has half-metallic behavior which is independent of the nanoribbon width. The opening of spin channels of the heterostructure depends on the matching of particular electronic orbitals in the Mo-dominated edges of ZMoS{sub 2}NR-H and ZMoS{sub 2}NR. Perfect spin filter effect appears at small bias voltages, and large negative differential resistance and rectifying effects are also observed in the heterostructure.
