DefectNet: MIT AI Model Trained on 2,000 Semiconductors Detects Six Coexisting Substitutional Defects

DefectNet, a foundation AI model from MIT trained on over 16,000 simulated vibrational spectra of 2,000 semiconductor materials, uses a custom attention mechanism to non‑destructively predict the chemical species and concentrations of up to six co‑existing substitutional defects, showing strong generalization on unseen 56‑element crystals and experimental data.
