As a point of comparison with traditional NEB-based studies, we used the DP 10 model to run an NEB calculation. Specifically, using O as a prototypical example, we compare the apparent diffusion energy barrier obtained from the MD simulation to the one that is obtained from a NEB calculation. We studied the diffusion of O on Ag (111) starting from the fcc site, the most stable site 65 diffusing to the hcp site. We observe a small energy mismatch between the DFT-predicted barrier and ML-predicted barrier, this is possibly due to higher total energy MAE error arising from the variety of systems and model training being more focused on reducing the force loss. The accuracy is also likely limited by the parameters and frameworks chosen for the MLP, we can sufficiently reduce the error with more optimal hyperparameters to reach near DFT-level accuracy.
