Fig.2 A model of the formation and stabilisation mechanism of the transition region.

Caption

Waters in the hydration layer above the upper terrace and transition zone are hydrogen bonded to each other and form a network. This extended hydrogen bonding network would be energetically favored, and Ca(OH)2 does not desorb from the surface because it is inhibited by this network. However, the energetic favorability of this extended layer would decrease as the distance from the step edge increases. Finally, Ca(OH) 2 desorbs at a point where its energy to desorb exceeds that of the Ca(OH)2. Finally, Ca(OH)2 desorbs at a point where the energy at which it attempts to desorb exceeds the energy of network stabilisation.
