Novel Electrical Characterization Method for Antiferroelectrics using a Positive Up Negative Down Approach
Grégoire Magagnin, Martine Le Berre, Sara Gonzalez +3
This study demonstrates the effectiveness of AFE-PUND, a revisited Positive Up Negative Down (PUND) protocol for characterizing antiferroelectric (AFE) materials, in analyzing $ZrO…
Unveiling structure-property correlations in ferroelectric films using variational autoencoders
Kévin Alhada-Lahbabi, Brice Gautier, Damien Deleruyelle +1
While (HZO) thin films hold significant promise for modern nanoelectronic devices, a comprehensive understanding of the interplay between their polycrystallin…
Comparative Performance of Fluorite-Structured Materials for Nanosupercapacitor Applications
Grégoire Magagnin, Jordan Bouaziz, Martine Le Berre +3
Over the last fifteen years, ferroelectric and antiferroelectric ultra thin films based on fluorite-structured materials have drawn significant attention for a wide variety of appl…
Ferroelastic twin angles at the surface of CaTiO quantified by PhotoEmission Electron Microscopy
G. Magagnin, C. Lubin, M. Escher +3
We use photoemission electron microscopy to measure the ferroelastic twin wall angles at the surface of CaTiO(001) and deduce the strain ordering. We analyze the angul…
