Subsequently, we have studied the influence of surface kinetics on the metals growth behaviour using a ReaxFF/kMC approach. The required activation energies and pre-exponential factors were computed utilising the developed ReaxFF potential and the implemented transition state tools. In the process, the nucleation and aggregation processes on Li(100) and Na(100) were analysed. By tracking the mean square displacement of the individual adatoms, we obtained the temperature and surface coverage dependent average diffusion coefficients.
