Curvature-Controlled Polarization in Adaptive Ferroelectric Membranes
Greta Segantini, Ludovica Tovaglieri, Chang Jae Roh +12
In this study, we explore the ferroelectric domain structure and mechanical properties of PbTiO-based membranes, which develops a well-ordered and crystallographic-oriented rip…

A multiscale Bayesian approach to quantification and denoising of energy-dispersive x-ray data
Pau Torruella, Abderrahim Halimi, Ludovica Tovaglieri +3
Energy dispersive X-ray (EDX) spectrum imaging yields compositional information with a spatial resolution down to the atomic level. However, experimental limitations often produce…

Assessing the nature of nanoscale ferroelectric domain walls in lead titanate multilayers
Edoardo Zatterin, Petr Ondrejkovic, Louis Bastogne +12
The observation of unexpected polarisation textures such as vortices, skyrmions and merons in various oxide heterostructures has challenged the widely accepted picture of ferroelec…
