Two-dimensional polarized MoTe₂/GeS heterojunction with an intrinsic electric field for photocatalytic water-splitting.

ABSTRACT: The construction of van der Waals heterostructures based on 2D polarized materials is a unique technique to achieve enhanced photocatalytic performance. We have investigated the intrinsic electric field and photocatalytic properties of the MoTe₂/GeS heterostructure via first-principles calculations. The results showed that a dipole-induced electric field induced by the GeS monolayer and an interface-induced electric field induced by the interface between the GeS monolayer and the MoTe₂ monolayer emerge in the 2D polarized MoTe₂/GeS heterostructure. The dipole-induced electric field contributes mainly to the total intrinsic electric field. Moreover, the 2D polarized MoTe₂/GeS heterostructure possesses many excellent and distinguished photoc
