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…
