Point defects in crystals act as molecules with distinct local structures & excitations. Following “Imperfections are not 0 K" doi.org/10.1039/D3CS..., Irea has trained ML force fields to explore the impact of temperature on defect thermodynamics #CompChem preprint at: arxiv.org/abs/2412.16741

(Right) a plot of the equilibrium defect concentration vs T
The main point is that vibrational contributions are significant.

What can be more digital alchemy than transforming from noise into a realistic material? #Chemeleon is our first #GenerativeAI model for crystals, and its architect is @hspark1212.bsky.social 🦎 #ChemSky #CompChemSky Preprint: chemrxiv.org/engage/chemr... Code: github.com/hspark1212/c...
