Yildiz Group's research focuses on laying the scientific groundwork and proof-of-principle material systems for the next generation of high-efficiency devices for energy storage and conversion and information processing, based on solid state ionic-electronic materials. We have thus far made significant contributions in advancing the molecular-level understanding of oxygen reduction and oxidation kinetics on mixed ionic-electronic solid surfaces. Specifically, we have uncovered the effects of elastic strain, dislocations, temperature and oxygen pressure on the reactivity and degradation of mixed ionic/electronic materials, by combining theoretical and experimental analyses of surface electronic structure, defect mobility and composition. The key findings in much of our work are obtained through our development of in-situ scanning tunnelling spectroscopy and x-ray spectroscopy methods in conjunction with first-principles calculations and novel atomistic simulations.
