APL materials 13 2, 021118 (2025)
This work focuses on the complex ferroelastic/ferroelectric domain structure in the prototypical ferroelectric PbTiO3 epitaxially strained on (110)o-oriented DyScO3 substrates, with a 22 nm-thick bottom SrRuO3 electrode. High quality epitaxial growth has been achieved from 7.2 nm (18 unit cells) up …

This study explores the ferroelectric domain structure and mechanical properties of PbTiO 3 ‐based membranes, which develop a well‐ordered and crystallographic‐oriented ripple pattern upon release from their growth substrate. The ferrolectric domain structure of the PbTiO…

Thèse, 222 (2024)
We here leverage scanning probe microscopy, sensitive to both structural and functional properties of ferroelectric domains, in order to change, measure, and characterise the variety of transitions (and transition-like behaviours in the highly nonlinear dynamics accompanying polarisation reversal…

Cette thèse explore, à l’aide de la microscopie à force atomique (AFM), le comportement des charges de surface sur les ferroélectriques, et la manière dont l’eau réagit selon l’orientation de la polarisation. En complément des techniques AFM, des développements matériels (contrôleur…

Nature communications 15 387 (2024)
Switchable tribological properties of ferroelectrics offer an alternative route to visualize and control ferroelectric domains. Here, we observe the switchable friction and wear behavior of ferroelectrics using a nanoscale scanning probe—down domains have lower friction coefficients and show…
