Abstract

The electronic and optical properties of the ZrS₂/SnS₂ van der Waals heterostructure have been investigated. We find out that the formed heterostructure has an intrinsic type-I band alignment. Moreover, the characteristics of optical absorption in the heterostructure can be enhanced to the amount of 10⁶ in the ultraviolet light region. In addition, the tuning electronic properties of ZrS₂/SnS₂ heterostructure are very interesting, due to the transitions from type-I to type-II band alignment that can occur by applying an external electric field. These results suggest that the atomically thin materials ZrS₂/SnS₂ heterostructure will be utilized for flexible optoelectronic applications.
