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
The paper demonstrates that adding an octahedral tilt to the antiferroelectric PbZrO₃ structure breaks symmetry and creates a ferrielectric polar phase, confirmed by first‑principl…
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…
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…
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…
Beware of the water: Hidden hydrogenation of perovskite membranes made by the water-soluble sacrificial layer method
Umair Saeed, Felip Sandiumenge, Kumara Cordero-Edwards +7
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…
