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…
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…
Tuning Coherent-Phonon Heat Transport in LaCoO/SrTiO Superlattices
D. Bugallo, E. Langenberg, E. Carbó-Argibay +6
Accessing the regime of coherent phonon propagation in nanostructures opens enormous possibilities to control the thermal conductivity in energy harvesting devices, phononic circui…
Deconvolution of phonon scattering by ferroelectric domain walls and point defects in a PbTiO3 thin film deposited in a composition-spread geometry
David Bugallo, Eric Langenberg, Elias Ferreiro-Vila +7
We present a detailed analysis of the temperature dependence of the thermal conductivity of a ferroelectric PbTiO3 thin film deposited in a composition-spread geometry enabling a c…
Ferroelectric 180 degree walls are mechanically softer than the domains they separate
Christina Stefani, Louis Ponet, Konstantin Shapovalov +7
Domain walls are functionally different from the domains they separate, but little is known about their mechanical properties. Using scanning probe microscopy, we have measured the…
The Exit-Wave Power-Cepstrum Transform for Scanning Nanobeam Electron Diffraction: Robust Strain Mapping at Subnanometer Resolution and Subpicometer Precision
Elliot Padgett, Megan E. Holtz, Paul Cueva +4
Scanning nanobeam electron diffraction (NBED) with fast pixelated detectors is a valuable technique for rapid, spatially resolved mapping of lattice structure over a wide range of…
Bi containing multiferroic perovskite oxide thin films
Rainer Schmidt, Eric Langenberg, Jofre Ventura +1
In this work multiferroic thin films of Bi containing perovskite oxides are discussed, where the driving force for ferroelectricity are the Bi3+ lone-pair electrons. First, a brief…
