The 12-6 Lennard Jones potential is used to describe the interaction between gold atoms and water molecules. While σ Au-O (= 3.6Å) is consistent with prior literature , ε Au-O is used as ad-justable parameter to achieve different wetting conditions. Interactions between water hydrogens and gold atoms are not present. This specific gold-water interaction potential was tailored by Merabia et al. to match the experimental wetting contact angle at 300K. ε Au-O used in their study was 0.0256eV. Since our simulations are performed at 370K, we observe a transition from partial to complete wetting at lower value of ε Au-O . To span both hydrophilic and hydrophobic conditions ε Au-O is selected from the set -{0.0128, 0.0112, 0.0096, 0.0080, 0.0064}eV. Even with the highest value of ε Au-O used in this study, we obtain a finite contact angle (see Figure ). Going forward, for ease of representation, a non-dimensional notation for ε Au-O is employed. ε * denotes the value of ε Au-O after normalizing it with 0.0128eV; therefore, ε * = 1 denotes the strongest and ε * = 0.5 the least wetting scenarios.
