The coexistence of negative and positive electrocaloric effect have been experimentally
demonstrated in lead-free 0.9 (K 0.5 Na 0.5) NbO 3-0.1 SrTiO 3 nanocrystalline ceramics …

Considering finite size effect, ferroelectric nanowires may show novel phenomena
compared to ferroelectric thin film and bulk. Here we investigated the effect of width and …

First-principles-based atomistic simulations are used to reveal ferroelectric phases and
phase transitions induced in a semiconductor ferroelectric, CsGeBr 3, by external loads …

Electrocaloric effect (ECE) of ferroelectrics has attracted considerable interest due to its

In an isothermal process, applying an electric field E to a ferroelectric material can change
its entropy S through two distinct mechanisms: namely, through changing the dipole …

Obtaining large electrocaloric (EC) effects in ferroelectric materials is a prerequisite for
incorporating them into advanced solid-state cooling devices. Based on phase-field …
