Assessing the nature of nanoscale ferroelectric domain walls in lead titanate multilayers
Edoardo Zatterin, Petr Ondrejkovic, Louis Bastogne +12
The observation of unexpected polarisation textures such as vortices, skyrmions and merons in various oxide heterostructures has challenged the widely accepted picture of ferroelec…
Giant voltage amplification from incipient ferroelectric states
Mónica Graf, Hugo Aramberri, Pavlo Zubko +1
Ferroelectrics subject to suitable electric boundary conditions present a steady negative capacitance response. When the ferroelectric is in a heterostructure, this behavior yields…
Domain Wall Orientations in Ferroelectric Superlattices Probed with Synchrotron X-Ray Diffraction
Marios Hadjimichael, Edoardo Zatterin, Stéphanie Fernandez-Peña +2
Ferroelectric domains in PbTiO/SrTiO superlattices were studied using synchrotron X-ray diffraction. Macroscopic measurements revealed a change in the domain wall orientati…
Charge doping and large lattice expansion in oxygen-deficient heteroepitaxial WO3
Giordano Mattoni, Alessio Filippetti, Nicola Manca +2
Tungsten trioxide is a versatile material with widespread applications ranging from electrochromic and optoelectronic devices to water splitting and catalysis of chemical reactions…
On the persistence of polar domains in ultrathin ferroelectric capacitors
Pavlo Zubko, Haidong Lu, Chung-Wung Bark +5
The instability of ferroelectric ordering in ultra-thin films is one of the most important fundamental issues pertaining realization of a number of electronic devices with enhanced…
Ground state oxygen holes and the metal-insulator transition in the negative charge transfer rare-earth nickelates
Valentina Bisogni, Sara Catalano, Robert J. Green +9
The metal-insulator transitions and the intriguing physical properties of rare-earth perovskite nickelates have attracted considerable attention in recent years. Nonetheless, a com…
