Accurate thermodynamic stability predictions enable data-driven computational materials design. Standard density functional theory
(DFT) approximations have limited accuracy with average errors of a few hundred meV/atom for ionic materials, such as oxides
and nitrides. Thus, insightful correction schemes as given by the coordination corrected enthalpies (CCE) method, based on an intuitive
parametrization of DFT errors with respect to coordination numbers and cation oxidation states, present a simple, yet accurate
solution to enable materials stability assessments. Here, we illustrate the computational capabilities of our AFLOW-CCE software by
utilizing our previous results for oxides and introducing new results for nitrides. The implementation reduces the deviations between
theory and experiment to the order of the room temperature thermal energy scale, i.e., ∼25 meV/atom. The automated corrections
for both materials classes are freely available within the AFLOW ecosystem via the AFLOW-CCE module, requiring only structural
inputs.
