In this study, highly monodisperse copper sulfide (CuS) quantum dots (QDs) have been successfully obtained using a ligand-chemistry strategy, and then a variety of S-deficient CuS/nitrogen-doped carbon (NC) heterointerfaces are constructed by compositional fine-tuning (CuS → CuS → Cu). First-principles calculations show that the S-deficient domains of CuS QDs and N-doped domains of carbon synergistically enhance the electron transfer from CuS to NC. In addition, the finite element simulations demonstrate that the diverse CuS QDs exhibit their intrinsic size and dielectric confinement effects to precisely manipulate the electric field distortion and improve the relaxation polarization.
