Upcoming Talk at EMA 2021

I’m looking forward to presenting an invited talk on order-disorder behavior in oxide thin films at the Electronic Materials & Applications 2021 Meeting! On January 20 @ 1515 EST, I’ll describe our research to understand synthesis pathways and degradation of oxide thin film interfaces in extreme environments, with implications for technologies such as fuel cells, quantum computing, and space-based electronics. My talk will be part of Symposium 4 – Complex Oxide Thin Films and Heterostructures: From Synthesis to Strain/Interface-engineered Emergent Properties.

From the abstract:

The development of advanced thin film synthesis techniques over the past several decades has sparked a renaissance in the design of nanomaterials for clean energy and quantum computing technologies. While it is now possible to produce oxide thin films in almost limitless configurations, engineering of desirable functionality for device applications depends on precise control of atomistic structure and defects. Complex synthesis pathways can lead to significant deviations from idealized structures, which occur at length scales that are challenging to probe experimentally and theoretically. This task is further compounded by dynamic changes imparted by processing steps and subsequent exposure to extreme environments. We have developed a materials design strategy based on state-of-the-art synthesis, ab initio modeling, and characterization, underpinned by aberration-corrected scanning transmission electron microscopy. I will describe our efforts to quantify and engineer nanoscale defect populations using unique insights from atomistic imaging and spectroscopy. Our results illustrate how the full range of information from modern electron microscopy can unlock promising new materials for energy storage, electronics, and computing.
