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…
Operando Electron Microscopy of Nanoscale Electronic Devices on Non-Conductive Substrates
Menglin Zhu, Michael Xu, Zishen Tian +7
Achieving operating conditions comparable to ``bulk'' electronic devices, such as thin film capacitors, during \textit{operando} electron microscopy remains challenging, particular…
phaser: A unified and extensible framework for fast electron ptychography
Colin Gilgenbach, Menglin Zhu, James M. LeBeau
We present \code{phaser}, an open-source Python package that provides a unified interface to both conventional and gradient descent-based ptychographic algorithms. Features such as…
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…
