December 7, 2023 - "Atomic Scale Understanding of Superconductivity in SrTiO3 and FeSe/SrTiO3"
Salva Salmani-Rezaie, Assistant Professor of Materials Science and Engineering, The Ohio State University
Abstract
Understanding quantum materials at the atomic scale is essential for bridging the gap between experimental observations and theoretical predictions. These materials encompass multiple degrees of freedom, including orbitals, lattices, spins, charges, and topology, leading to a rich tapestry of emergent phenomena and states of matter. One such phenomenon is superconductivity.
This talk focuses on the atomic-scale understanding of superconductivity in SrTiO3 and FeSe/SrTiO3. Electron microscopy faces limitations (temperature range and electromagnetic lenses) in studying superconducting state. I talk about how understanding the normal state structure sheds light on the nature of superconductivity in SrTiO3 and elucidates the role of interfaces in enhancing superconductivity in FeSe. By integrating electron microscopy with other techniques, we demonstrate its significant role in revealing the nature of superconductivity and providing a comprehensive understanding of quantum materials, connecting atomic structures to the emergence of exotic properties.
Biographical Information
Salva Salmani-Rezaie is currently an Assistant Professor at the Department of Materials Science at The Ohio State University. Prior to this role, she was a Kavli postdoctoral fellow at Cornell University. She received her Ph.D. in materials science from the University of California, Santa Barbara in 2021. Her current research is primarily focused on utilizing electron microscopy techniques to gain atomic-scale insight into quantum and topological phenomena, Emergent phenomena in functional oxides (ferroics and superconductors) and symmetry-property correlation in topological materials. Her work also involves seeking functional defects for quantum information applications and Cryogenic microscopy of quantum materials.
