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…
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…
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…
