History-dependent and frequency-dependent dielectric nonlinearities induced by polar nanoregions in a thin film of 0.5 ( Ba 0.7 Ca 0.3 TiO 3 ) -- 0.5 ( BaZr 0.2 Ti 0.8 O 3 )
Kevin Nadaud, Guillaume Nataf, Nazir Jaber +3
In this article, dielectric nonlinearities in 0.5(Ba0.7 Ca0.3 TiO3 ) -- 0.5(BaZr 0.2 Ti0.8 O3 ) thin film are studied using impedance spectroscopy and harmonic measurements, as a f…
Domain-wall driven suppression of thermal conductivity in a ferroelectric polycrystal
Rachid Belrhiti-Nejjar, Manuel Zahn, Patrice Limelette +8
A common strategy for reducing thermal conductivity of polycrystalline systems is to increase the number of grain boundaries. Indeed, grain boundaries enhance the probability of ph…
Tunable electrocaloric effect in lead scandium tantalate through calcium doping
Youri Nouchokgwe, Natalya S. Fedorova, Pranab Biswas +11
State-of-the-art electrocaloric cooling prototypes rely on the conventional electrocaloric effect of ferroelectric lead scandium tantalate (PbSc0.5Ta0.5O3, PST), which peaks near r…
Lead-free room-temperature ferroelectric thermal conductivity switch using anisotropies in thermal conductivities
Lucile Féger, Carlos Escorihuela-Sayalero, Jean-Michel Rampnoux +11
Materials with on-demand control of thermal conductivity are the prerequisites to build thermal conductivity switches, where the thermal conductivity can be turned ON and OFF. Howe…
Enhancement of piezoelectric properties in a narrow cerium doping range of evidenced by high throughput experiment
Kevin Nadaud, Guillaume F. Nataf, Nazir Jaber +5
Lead-free materials based on the (BCZT) system exhibit excellent electromechanical properties that can be strongly modified by small amounts of dopants…
Subcoercive-field dielectric response of thin film: peculiar third harmonic signature of phase transitions and residual ferroelectricity
Kevin Nadaud, Guillaume F. Nataf, Nazir Jaber +5
Sub-coercive field non-linearities in (BCTZ 50/50) thin film elaborated using…
