Scaling law for electrocaloric temperature change in antiferroelectrics
A combination of theoretical and first-principles computational methods, along with experimental evidence from the literature, were used to predict the existence of a scaling law for the electrocaloric temperature change in antiferroelectric materials. We show that the temperature change scales quadratically with electric field, allowing a simple transformation to collapse the set of ΔT(E) onto...
متن کاملTHE SCALING LAW FOR THE DISCRETE KINETIC GROWTH PERCOLATION MODEL
The Scaling Law for the Discrete Kinetic Growth Percolation Model The critical exponent of the total number of finite clusters α is calculated directly without using scaling hypothesis both below and above the percolation threshold pc based on a kinetic growth percolation model in two and three dimensions. Simultaneously, we can calculate other critical exponents β and γ, and show that the scal...

متن کاملGiant electrocaloric effect in ferroelectric nanotubes near room temperature
Ferroelectric perovskite oxides possess large electrocaloric effect, but only at high temperature, which limits their potential as next generation solid state cooling devices. Here, we demonstrate from phase field simulations that a giant adiabatic temperature change exhibits near room temperature in the strained ferroelectric PbTiO₃ nanotubes, which is several times in magnitude larger than th...
متن کاملScaling law
Scaling law for the Υ(4S) → B ¯ B and ψ(3770) → D ¯ D decay constants from effective sum rules Abstract Sum rules for exclusive production of heavy meson pairs in e + e − annihilation are used to evaluate the Υ(4S) → B ¯ B and ψ(3770) → D ¯ D decay widths. Infinitely heavy quark limit is discussed, so that scaling law for the quarkonium-meson coupling constant is derived. A value of the B ¯ B p...
