Yildiz Group focuses on laying the scientific groundwork and proof-of-principle material systems for the next generation of high-efficiency devices for energy conversion and information processing, based on solid state ionic-electronic materials. The scientific insights derived from our research impact the design of novel materials and interfaces to enable high-energy-efficiency and long-life of:
– solid oxide fuel cells, and electrolytic splitting of water and CO₂
– brain-inspired analog computing, memristive information storage and logic
– solid state batteries
– corrosion and hydrogen resistant films

We have made significant contributions in advancing the molecular-level understanding of oxygen reduction, oxidation, ion diffusion and intercalation, and charge transfer on mixed ionic-electronic solids. We have uncovered the effects of elastic strain, dislocations, and strong electric fields on the reactivity, efficiency, and degradation of mixed ionic-electronic materials in these applications. In doing so, our approach combines theoretical, computational and experimental analyses of electronic structure, defect mobility and composition.
