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…
Interface-resolved structural properties of epitaxial YFeO/ GdFeO bilayers grown on GGG(111) by pulsed laser deposition
Kshitij Singh Rathore, Abhisek Mishra, Swayang Priya Mahanta +10
Epitaxial YFeO (YIG) and GdFeO (GdIG) thin films, along with their bilayer heterostructures, were grown on GdGaO(GGG)(111) substrates u…
Complex polar superstructure controlled thermal conductivity in ferroelectric PbTiO3/SrTiO3 superlattices
Noa Varela-Domínguez, Marcel S. Claro, Araceli Gutiérrez-Llorente +8
Integrating epitaxial thin films of ferroelectric PbTiO3 and paraelectric SrTiO3 into artificially layered periodic superlattices provides a unique platform for tuning strain, depo…
Enhanced Photocurrent Response in Epitaxial 0.5PZT-0.5PFN Multiferroic Thin Films
Lucia Imhoff, Miguel A. Rengifo, Jose M. Caicedo Roque +4
The exploration of novel multiferroic materials with strong coupling between ferroelectric polarization and photovoltaic effects is crucial for next-generation optoelectronic devic…
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…
Device-area selection of memristive transport regimes in epitaxial -based ferroelectric devices
Priscila A. Tapia Presas, Lautaro Galarregui, Wilson Román Acevedo +5
Ferroelectric memristive devices based on hafnia are promising systems for neuromorphic electronics, yet the interplay between polarization-modulated resistive changes and defect-m…
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…
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…
