'energy above hull'

[dingyiming8]

Hello, I would like to ask about the explanation of the model in the paper. In the appendix on perovskite stability, is the name in the last column written incorrectly? It should be 'energy above hull' rather than 'formation energy'.

Hello @dingyiming8 , I’m not sure what the author intended, but here I listed some links that I found regarding the relationship between energy above hull and formation energy.
The theory/calculation behind energy-above-hull: how to calculate for quarternary structures?
Energy of formation Vs Formation Energy Vs Heat of Formation Vs Energy Above Hull differences
Formation energy and Energy above convex hull as indicators of stability

thank you，I will see it
