Influence of thermal conditions on the electrocaloric effect in a multilayer capacitor based on doped BaTiO3
We present the results of studies of thermal expansion, heat capacity, permittivity, polarization and the influence of different thermal conditions on the intensive electrocaloric effect (ECE), Δ T AD , in a commercial multilayer capacitor based on doped BaTiO3. Investigations in a wide temperature...
