Fig. 2. z-Component of the force at the center of mass (right panels) as a function of the vertical displacement for different water configurations (left panels): (a) “flat”, (b) “up”, (c) “flat-up”, (d) “perpendicular” and (e) “down”. The vertical displacement is given with respect to the Au–O distance in the ground state. The insets of the right panels show the regions in each graph for which FCMz = 0.
