    • Although the (formula presented) and (formula presented) models (numbered 17 and 18, respectively) have acceptable (formula presented)‘s and (formula presented)‘s, their final configurations are close to that of the optimized (formula presented) model. Therefore, we discuss only the (formula presented) model

    • We emphasize that we are not implying that there are two distinct types of surface Al atoms. Instead, we use two Al domains in the split-position model to overcome the inability of the LEED simulations to model highly anisotropic vibrations. Physically, the atomic positions derived are simply the average positions of the two domains

    • While including the diffractionally inequivalent terraces in the split-position model may have lowered the Pendry R factor, we believe that the structural results would not be significantly altered

    • Since we also considered essentially this model (O1) and found it to be unacceptable, clearly our surface was not fully hydrated
