a Profile of the planar averaged self-consistent electrostatic potential for the ZrS2/B20 as a function of position in the z-direction. b 3D charge density difference for the ZrS2/B20 nanocomposite with an isovalue of 0.004 e/Å3. Blue and green isosurfaces represent charge accumulation and depletion in the space. c Profile of the planar averaged charge density difference for the ZrS2/B20 as a function of position in the z-direction. The horizontal lines denote the central location of each atomic layer
