Beware of the water: Hidden hydrogenation of perovskite membranes made by the water-soluble sacrificial layer method
Umair Saeed, Felip Sandiumenge, Kumara Cordero-Edwards +5
The fabrication of perovskite oxide free-standing films (membranes) by lift-off methods using water-soluble sacrificial layers is appealing because of the new mechanical degrees of…
Polarization Vortices in a Ferromagnetic Metal via Twistronics
Yingzhuo Lun, Xinxin Hu, Qi Ren +15
Recent advances in moire engineering provide new pathways for manipulating lattice distortions and electronic properties in low-dimensional materials. Here, we demonstrate that twi…
Ultrafast decoupling of polarization and strain in ferroelectric BaTiO
Le Phuong Hoang, David Pesquera, Gerard N. Hinsley +20
A fundamental understanding of the interplay between lattice structure, polarization and electrons is pivotal to the optical control of ferroelectrics. The interaction between ligh…
Hierarchical domain structures in buckled ferroelectric free sheets
David Pesquera, Kumara Cordero-Edwards, Marti Checa +11
Flat elastic sheets tend to display wrinkles and folds. From pieces of clothing down to two-dimensional crystals, these corrugations appear in response to strain generated by sheet…
Coexistence of ferroelectric and ferrielectric phases in ultrathin antiferroelectric PbZrO3 thin films
Ying Liu, Ranming Niu, Roger Uriach +7
Whereas ferroelectricity may vanish in ultra-thin ferroelectric films, it is expected to emerge in ultra-thin anti-ferroelectric films, sparking people's interest in using antiferr…
Freestanding perovskite and infinite-layer nickelate membranes
Hoshang Sahib, Laurent Schlur, Kumara Cordero +3
Following the discovery of superconductivity in hole-doped NdNiO infinite-layer thin films, extensive research has been conducted particularly to compare these materials with c…
Switching dynamics and improved efficiency of free-standing antiferroelectric capacitors
Umair Saeed, David Pesquera, Ying Liu +7
We report the switching dynamics of antiferroelectric Lead Zirconate (PbZrO3) free standing capacitors compared to their epitaxial counterparts. Frequency dependence of hysteresis…
Probing the Surface Polarization of Ferroelectric Thin Films by X-ray Standing Waves
Le Phuong Hoang, Irena Spasojevic, Tien-Lin Lee +7
Understanding the mechanisms underlying a stable polarization at the surface of ferroelectric thin films is of particular importance both from a fundamental point of view and to ac…
