WebJan 1, 2024 · Here, we identified the thermodynamic phase diagram of heterostructural (Alx Ga 1-x) 2 O 3 alloy. Using density-functional theory (DFT) calculations and regular solution model, we calculated the Gibbs-free energy of mixing of heterostructural polymorphs. Based on the calculation, we show the phase diagram of (Al x Ga 1-x) 2 O 3 alloy system ...
