About us

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.

Our diversity statement

Inclusivity of diversity is a necessary condition for creating a healthy environment. A healthy environment fosters motivation, innovation and well-being. Our group is committed to actively embracing the whole spectrum of diversity, including race, gender, disabilities, family condition, national origin, religion, sexual orientation, and skin color, among other attributes. Not only do we strive to have open discussions and take actions about scientific topics but also about how to promote diversity in our field, concerns about future careers, ways to improve our group culture, and ways to attract a diverse group of new group members. We can only be equipped appropriately to tackle the most challenging problems by integrating diverse points of view and by drawing from wide-ranging personal experiences.
