Uniaxial strain tuning of functional properties in antiferroelectric PbZrO3 membrane capacitors
Umair Saeed, Huazhang Zhang, David Pesquera +5
Lead zirconate (PbZrO3, PZO) is a prototypical antiferroelectric (AFE) system promising for applications such as energy storage and neuromorphic computing. However, in conventional…
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…
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…
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…
Photostrictive actuators based on freestanding ferroelectric membranes
Saptam Ganguly, David Pesquera, Daniel Moreno Garcia +9
Complex oxides offer a wide range of functional properties, and recent advances in fabrication of freestanding membranes of these oxides are adding new mechanical degrees of freedo…
