Quasicrystalline oxide interfaces by twisting SrTiO3 membranes
Shivasheesh Varshney, Sooho Choo, Huan Liu +34
Quasicrystals reveal that long-range order can exist without translational periodicity, but deterministic routes for designing strongly bonded quasicrystalline interfaces remain un…
Anion Ordering and Phase Stability Govern Optical Band Gaps in BaZr(S,Se)3
Erik Fransson, Michael Xu, Prakriti Kayastha +6
Chalcogenide perovskites have emerged as promising lead free materials for photovoltaic and thermoelectric applications. Among them, BaZrS3 has attracted particular attention due t…
Direct determination of antiferroelectric-to-ferroelectric phase transition pathways in PbZrO with Operando Electron Microscopy
Menglin Zhu, Michael Xu, Louis Alaerts +5
Under a sufficiently high applied electric field, a non-polar antiferroelectric material, such as \ce{PbZrO3}, can undergo a rapid transformation to a polar ferroelectric phase. Wh…
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…
Two-dimensional photonic crystal cavities in ZnSe quantum well structures
Siqi Qiao, Nils von den Driesch, Xi Chen +7
ZnSe and related materials like ZnMgSe and ZnCdSe are promising II-VI host materials for optically mediated quantum information technology such as single photon sources or spin qub…
Sampling metrics for robust reconstructions in multislice ptychography: Theory and experiment
Colin Gilgenbach, Xi Chen, James M. LeBeau
While multislice electron ptychography can provide thermal-vibration limited resolution and 3D information, it relies on the proper selection of many intertwined experimental and c…
