Accelerated Dopant Screening in Oxide Semiconductors via Multi-Fidelity Contextual Bandits and a Three-Tier DFT Validation Funnel

Researchers have developed a multi-fidelity contextual bandits approach to screen doped oxide semiconductors, significantly reducing computational costs while identifying optimal dopant combinations for visible-light-range band gaps. This method enables efficient exploration of vast combinatorial spaces crucial for applications in photocatalysis and optoelectronics, offering developers tools to predict material performance across different hosts based on chemical dimensions.
