In this work, we demonstrate large and tunable near-field electrostatic effects of self-assembled organic layers and 2D materials, and develop a theory for describing and understanding of those effects. We derive analytical expressions for the in-plane potential superlattices and out-of-plane electric fields, and show their applicability in tuning the electronic structure of 2D materials and moiré structures.
