What Has Been Achieved:
We developed and validated a ReaxFF description for Ba/SrTiO3 perovskites.
Importance of the Achievement:
These ReaxFF parameters can be straightforwardly combined with existing ReaxFF descriptions for Mo/W/Se/S/C/O/H, enabling simulations of MoWSeS-material growth on STO support.
Unique Feature(s) of the MIP that Enabled this Achievement:
This work responds to a continuing external user interest in ReaxFF parameters for 2D materials and their growth substrates
