To the best of our knowledge, studies of growth mechanisms for similar systems tend to be carried out using kinetic Monte Carlo (kMC) or mean field approximation methods, with some studies choosing to use classical molecular dynamics. However, as the growth mechanism is governed by the competition between the adatom-substrate and the adatom-adatom interaction, we can use these in combination with the strength of adhesion and selected ab initio molecular dynamics (aiMD) simulations, which account for temperature effects, to predict the likely growth mechanism and avoid expensive activation energy calculations.
