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…

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…
