Breakdown and polarization contrasts in ferroelectric devices observed by operando laser-based photoemission electron microscopy with the AC/DC electrical characterization system
Hirokazu Fujiwara, Yuki Itoya, Masaharu Kobayashi +2
We have developed an operando laser-based photoemission electron microscope (laser-PEEM) with a ferroelectric characterization system. A Sawyer-Tower circuit was implemented to mea…

Non-Destructive Imaging of Breakdown Process in Ferroelectric Capacitors Using \textit{In-situ} Laser-Based Photoemission Electron Microscopy
Hirokazu Fujiwara, Yuki Itoya, Masaharu Kobayashi +3
HfO-based ferroelectrics are one of the most actively developed functional materials for memory devices. However, in HfO-based ferroelectric devices, dielectric breakdown i…
