Mixed MAPbI_(3-x)Br_x database for force field training
Crystal structures obtained during the on-the-fly MLFF heating molecular dynamics simulations of the MAPbX3 (X=I,Br) and its mix MAPbI1.5Br1.5 hybrid perovskites of Fykouras et.al.
The automatically picked up reference structures set creates a minimal training database (containing total energies, forces, stress tensors and atomic coordinates) for machine-learning or classical force field development. See the README file for details about the structure and the applied electronic structure method.
