Electrocaloric effects in multilayer capacitors of stoichiometric lead scandium tantalate with varying B‑site cation order
Multilayer capacitors (MLCs) of stoichiometric lead scandium tantalate (PbSc0.5Ta0.5O3 or PST) have been shown to generate large thermal changes (known as electrocaloric, or EC, effects) in response to large changes in applied electric fields sustained without breakdown. These MLCs represent a …

Annealing studies of detector materials for uncooled thermal imaging
… elements are machined from bulk ceramic, either lead zirconate titanate (PZT) or lead scandium tantalate (PST), and then flip-chip bonded to a readout IC (ROIC). Since this is equipment and labour intensive, detectors are expensive to produce and, in addition, the detector structures used limit …

Electrocaloric applications based on multilayer capacitors of PbSc₀.₅Ta₀.₅O₃
Solid-state refrigerants that exhibit electrically driven reversible thermal changes, known as electrocaloric (EC) effects, represent a potentially eco-friendly alternative to the greenhouse gases currently used as refrigerants in refrigerators and heat pumps. The phenomenology of EC effects is …

Electrocaloric materials and devices
The temperature and/or entropy of electrically polarisable materials can be altered by changing electric field E. Research into this electrocaloric (EC) effect has focussed on increasing the size of the EC effects, with the long-term aim of building a cooler with an EC material at its heart. …
