In Situ Hrtem
ASCENT work from the 2020 Symposia on VLSI Technology and Circuits, held in June, has been featured as a research highlight in Nature Electronics. Georgia Institute of Technology Professor and ASCENT PI, Asif Khan, and PhD Student Sarah Lombardo, led this international team effort which uses in situ high-resolution transmission electron microscopy to study the nature of electric-field-driven polarization switching in antiferroelectric ZrO2 at the atomic scale. Sarah is co-advised by Professor Kacher of Georgia Institute of Technology. The TEM work was performed at the Oak Ridge National Laboratory’s Center for Nanophase Materials Sciences, a Department of Energy (DOE) Office of Science User Facility. ASCENT PIs Professor Andrew Kummel, Professor Kyeongjae Cho, and postdoc Dr Kisung Chae were also involved in the collaborative effort.
