Machine learning models accelerate semiconductor defect analysis

Researchers have developed machine learning models to predict defect formation energies and zero-phonon lines in semiconductors, specifically for 4H-SiC. These models aim to accelerate high-throughput workflows by acting as a prescreening step, reducing the need for costly density-functional theory (DFT) calculations. The models achieved mean absolute errors of 0.437 eV for formation energy and 0.202 eV for zero-phonon lines in vacancy and substitution defect systems, showing potential for direct application beyond prescreening.
