Figure 2. The density distribution of oxygen atoms in the water near the surfaces. The position of the plane where the hydroxyl oxygen atoms on the surface are located is defined as the reference (z = 0 Å). The black, red, blue and olive curves correspond to δq = 0 e, δq = 0.2 e, δq = 0.4 e and δq = 0.6 e, respectively.
