Functional Dislocations

Maryam Ghazisaeidi,
Distinguished Professor of Engineering in Materials Science and Engineering and Professor in Physics at Ohio State

Abstract: Dislocations are line defects in crystals that, while traditionally seen as detrimental to electronic materials, offer intriguing possibilities for enhancing functionality. Although dislocations have been extensively studied in structural materials for their role in plasticity, they are often viewed as harmful in electronic devices, leading to efforts to eliminate them. However, the atomic distortion near dislocation cores creates a unique environment that can stabilize electronic and magnetic states otherwise unattainable in bulk crystals. In this talk, I will explore this potential, using photoplasticity in ZnS as a key example. Photoplasticity refers to a brittle to ductile transition under varying light conditions. I will provide a possible mechanism for this phenomenon using first-principles calculations and discuss how the theory can be supported by experiments. Additionally, I will discuss how dislocations can be purposefully leveraged in materials like diamond to engineer quantum-relevant functionalities.

Behind the scenes: stories of atoms forming next generation materials

Giulia Galli,

Liew Family Professor of Electronic Structure and Simulations, University of Chicago Pritzker School of Molecular Engineering & Director of the Midwest Integrated Center for Computational Materials, Argonne National Laboratory

Abstract: Materials are enablers of innovation and have brought about revolutionary changes to society: familiar examples are silicon used in transistors and metal oxides in batteries, devices that have become omnipresent in our daily lives. In this talk we explore how the fundamental understanding of the way atoms interact in materials leads to predicting forms of matter that enable next generation technologies. We achieve such insights by combining quantum mechanics, high performance computers and by closely collaborating with experimentalists. I will address two outstanding challenges: the design of cheap and easily fabricated materials that efficiently capture solar energy, and the discovery of radically novel sensors and computers to swiftly move into the quantum information age.


Bio: She is the Liew Family Professor of Electronic Structure and Simulations in the Pritzker School of Molecular Engineering and the Department of Chemistry at the University of Chicago, and a Senior Scientist at Argonne National Laboratory, where she is the director of the Midwest Integrated Center for Computational Materials (https://miccom-center.org/). She is an expert in the development of theoretical and computational methods to predict and engineer material and molecular properties using quantum simulations (https://galligroup.uchicago.edu/). She is a member of the US National Academy of Sciences, the American Academy of Arts and Science, and the International Academy of Quantum Molecular Science, and Fellow of the American Association for the Advancement of Science and of the American Physical Society (APS). Her recognitions include the Material Research Society Theory Award, the David Adler Award and Aneesur Rahman Prize from the American Physical Society, the Feynman Nanotechnology Prize in Theory, and the Hirschfelder Prize in theoretical chemistry.
