For the purpose of this study, we show the static bilayer results as a range to account for these uncertainties. Additionally, in this range we include the energy difference due to the orientation of water. As a result, the lowest energy is taken as the most stable configuration between the H-down and H-up calculations and the entropy is taken as 0.38 eV. Oppositely, the highest energy is taken as the least stable configuration and the entropy is taken as 0.67 eV.
