The stability and electronic structures of the arsenene/WS2 van der Waals heterostructure at different electrical field intensities and strains were investigated via the first-principles calculation based on the density functional theory. The calculation results show that the arsenene/WS2 heterostructure possesses a type-II band alignment and an indirect band gap. Moreover, the external electrical field modulates the band gap and brings the band alignment transition from type-Ⅱ to type-Ⅰ in the heterostructure. In addition, the band gap can be effectively tuned by the strain, while the type-Ⅱ band alignment is robust under the strain.
