Depth-Resolved Evolution of Buried Polar Topologies in a PbTiO3/SrTiO3 Superlattice
Xinxin Hu, Penghan Lu, Noa Varela-Dominguez +9
Polar topologies in complex oxides gives rise to a rich spectrum of emergent functionalities and are fundamentally governed by three-dimensional (3D) atomic structures. However, di…
Tilt-driven ferrielectricity in PbZrO
Huazhang Zhang, Ying Liu, Carson Carroll +6
We reveal a tilt-driven mechanism for ferrielectricity in prototypical antiferroelectric PbZrO. Specifically, introducing an additional octahedral tilt into the antiferroelectr…
Domain-induced control of latent heat in freestanding BaTiO membranes
Tapas Bar, David Pesquera, Arnau Villalobos-Martin +11
Thin ferroelectric BaTiO films often exhibit continuous transitions instead of the first-order behavior of bulk crystals, a discrepancy usually attributed to epitaxial strain o…
Direct spatiotemporal imaging of carriers reveals a long-lived bulk photovoltaic mechanism
Saptam Ganguly, Sebin Varghese, Aaron M. Schankler +6
The bulk photovoltaic effect (BPVE), a manifestation of broken centrosymmetry, has attracted interest as a probe of the symmetry and quantum geometry of materials, and for use in p…
Disorder-aided Early Warning Signals: Predicting Catastrophic Shifts in Athermal Systems
Tapas Bar, Anurag Banerjee, Blai Casals +2
The early prediction of tipping points, distinguished by sudden and catastrophic shifts from stable states, poses a challenging task that would enable us to assess the impending th…
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…
Vortices and antivortices in antiferroelectric PbZrO3
Ying Liu, Huazhang Zhang, Konstantin Shapovalov +8
Although ferroelectric materials are characterised by their parallel arrangement of electric dipoles, in the right boundary conditions these dipoles can reorganize themselves into…
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…
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…
