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…

Band gap tuning by structural phase transition in Sm-substituted BiFeO3 powders
Christina Hill, Michele Melchiorre, Cosme Milesi-Brault +6
The substitution of bismuth by samarium in BiFeO3 is known to induce a structural phase transition from the polar phase to a non-polar phase, with a possible antiferroelectric inte…
