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…
Complex polar superstructure controlled thermal conductivity in ferroelectric PbTiO3/SrTiO3 superlattices
Noa Varela-Domínguez, Marcel S. Claro, Araceli Gutiérrez-Llorente +8
Integrating epitaxial thin films of ferroelectric PbTiO3 and paraelectric SrTiO3 into artificially layered periodic superlattices provides a unique platform for tuning strain, depo…
Boosting the Memory Window of Memristive Stacks via Engineered Interfaces with High Ionic Mobility
José Diogo Costa, Daniel Veira-Canle, Noa Varela-Domínguez +8
Realizing the potential of oxide-based memristive devices for high-density data storage and energy-efficient computing still relies on overcoming key technical challenges, includin…
van der Waals epitaxy of lead monoxide - PbO and application as a virtual substrate for oxide membranes
Marcel S. Claro, Francisco Rivadulla
We report the successful growth of epitaxial layers of van der Waals (vdW) lead oxide (PbO) polymorphs on different substrates, via pulsed laser deposition. A thin layer of vdW …
The coupling of polarization and oxygen vacancy migration in ferroelectric Hf0.5Zr0.5O2 thin films enables electrically controlled thermal memories above room temperature
Didac Barneo, Rafael Ramos, Hugo Romero +5
Here we investigate epitaxial Hf0.5Zr0.5O2 ferroelectric thin films as potential candidates to be used as non-volatile electric-field-modulated thermal memories. The electric-field…
Oxygen vacancies in strained SrTiO thin films: formation enthalpy and manipulation
L. Iglesias, A. Sarantopoulos, C. Magen +1
We report the enthalpy of oxygen vacancy formation in thin films of electron-doped SrTiO, under different degrees of epitaxial stress. We demonstrate that both compressive an…
