Recently,the atomically thin 2D layered transition-metal dichalcogenides 1H-XT2(X=Mo,W; T=S,Se,Te)have been studied extensively due to their unique properties.1-3 In this work,the electronic structure of black phosphorene(BP)/monolayer 1H-XT2(X=Mo,W; T=S,Se,Te)two dimensional (2D)van der Waals heterostructures have been calculated by the first-principles method.It is found that the electronic band structures of both BP and XT2 are preserved in the combined van der Waals heterostructures.The WSe2/BP van der Waals heterostructure demonstrates the type-Ⅰ band alignment,but the MoS2/BP,MoSe2/BP,MoTe2/BP,WS2/BP and WTe2/BP van der Waals heterostructures demonstrate the type-II band alignment.Especially,the n-type XT2/p-type BP van der Waals heterostructures can be applied into the p-n diode and logical devices.The strong spin splitting appears in all of the heterostructures by considering the spin orbital coupling(See Fig.1). Our results play a significant role in the prediction of novel 2D van der Waals heterostructures that have potential applications in the spin-filter devices,spin field effect transistor and optoelectronic devices,etc.
