Thermodynamic origin of medium-entropy stabilization in multicomponent rock-salt oxides
First-principles thermodynamic analysis shows medium-entropy rock-salt oxides (three to four cations) become stable at high temperature via entropy-driven Gibbs free energy reduction, unlike the two-cation enthalpy-stabilized case.
