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…
Local and correlated studies of humidity-mediated ferroelectric thin film surface charge dynamics
Iaroslav Gaponenko, Loïc Musy, Neus Domingo +4
Electrochemical phenomena in ferroelectrics are of particular interest for catalysis and sensing applications, with recent studies highlighting the combined role of the ferroelectr…
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…
Periodicity doubling cascades: direct observation in ferroelastic materials
Arnoud S. Everhardt, Silvia Damerio, Jacob A. Zorn +6
Very sensitive responses to external forces are found near phase transitions. However, phase transition dynamics and pre-equilibrium phenomena are difficult to detect and control.…
Giant reversible nanoscale piezoresistance at room temperature in Sr2IrO4 thin films
Neus Domingo, Laura López-Mir, Marcos Paradinas +10
Layered iridates have been the subject of intense scrutiny on account of their unusually strong spin-orbit coupling, which opens up a narrow gap in a material that would otherwise…
