title: Multifunctional heterostructures constructed using MoS2and WS2nanoribbons.
abstract: Using first-principles calculations based on nonequilibrium Green's function together with density functional theory, we investigated the electronic transport properties of some devices consisting of armchair and zigzag MoS2NRs/WS2NRs in-plane heterostructures. The results indicate that these heterostructures exhibit rectifying performance, which are depressed as the number of WS2NR unit cell decreases. In addition, the NDR effect is observed and can be modulated. Importantly, the zigzag MoS2NRs/WS2NRs heterostructures can be used as spintronic devices because of their tunable spin filtering behavior and NDR effect. The devices with WS2NRs electrode display a better NDR effect and spin filtering behavior. The unique properties of these heterostructures suggest promising applications in the next generation nanoelectronic devices.
