Sensitivity of Multislice Electron Ptychography to Point Defects: A Case Study in SiC
Aaditya Bhat, Colin Gilgenbach, Junghwa Kim +3
Here, we evaluate multislice electron ptychography as a tool to carry out depth-resolved atomic resolution characterization of point defects, using silicon carbide as a case study.…
Bridging experiment and theory of relaxor ferroelectrics at the atomic scale with multislice electron ptychography
Menglin Zhu, Michael Xu, Yubo Qi +7
Introducing structural and/or chemical heterogeneity into otherwise ordered crystals can dramatically alter material properties. Lead-based relaxor ferroelectrics are a prototypica…
Atomic Structure of Self-Buffered BaZr(S,Se) Epitaxial Thin Film Interfaces
Michael Xu, Kevin Ye, Ida Sadeghi +2
Understanding and controlling the growth of chalcogenide perovskite thin films through interface design is important for tailoring film properties. Here, the film and interface str…
Additively manufacturable high-strength aluminum alloys with thermally stable microstructures enabled by hybrid machine learning-based design
S. Mohadeseh Taheri-Mousavi, Michael Xu, Florian Hengsbach +8
Additively manufactured (AM) aluminum alloys with high strength and thermal stability have broad applications in turbine engines, vacuum pumps, heat exchangers, and many other indu…
A Processing Route to Chalcogenide Perovskites Alloys with Tunable Band Gap via Anion Exchange
Kevin Ye, Ida Sadeghi, Michael Xu +6
We demonstrate synthesis of BaZr(S,Se)3 chalcogenide perovskite alloys by selenization of BaZrS3 thin films. The anion-exchange process produces films with tunable composition and…
Insights into Chemical and Structural Order at Planar Defects in a Functional Oxide Using Multislice Electron Ptychography
Menglin Zhu, Michael Xu, Yu Yun +7
Switchable order parameters in ferroic materials are essential for functional electronic devices, yet disruptions of the ordering can take the form of planar boundaries or defects…
