Quantitative correlation between structural (dis-)order and diffuseness of phase transition in lead scandium tantalate
T. Granzow, A. Aravindhan, Y. Nouchokgwe +9
Ferroelectrics show a phase transition to a paraelectric phase at a well-defined transition temperature. Introducing disorder makes this transition diffuse, and the system becomes…
Solution-Based Fabrication of High-Performance KNaNbO Thin Films for Surface Haptics
Nagamalleswara Rao Alluri, Longfei Song, Stephanie Girod +8
KNaNbO is among the most promising lead-free piezoelectrics. While its sputtered films match the performance of the champion piezoelectric Pb(Zr,Ti)O, repro…
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…
Ferroelectric HfO-ZrO multilayers with reduced wake-up
Barnik Mandal, Adrian-Marie Philippe, Nathalie Valle +3
Since the discovery of ferroelectricity in HfO thin films, significant research has focused on Zr-doped HfO and solid solution (Hf,Zr)O thin films. Functional propertie…
Giant Strain Tunability in Polycrystalline Ceramic Films via Helium Implantation
A. Blàzquez Martínez, S. Glinšek, T. Granzow +5
Strain engineering is a powerful tool routinely used to control and enhance properties such as ferroelectricity, magnetic ordering, or metal-insulator transitions. Epitaxial strain…
