Title: Ultrafast Electric Field Pulse Control of Giant Temperature Change in Ferroelectrics

Abstract

There is a surge of interest in developing environmentally friendly solid-state-based cooling technology. Here, we point out that a fast cooling rate (≈ 10 11 K/s) can be achieved by driving solid crystals to a high-temperature phase with a properly designed electric field pulse. Specifically, we predict that an ultrafast electric field pulse can cause a giant temperature decrease up to 32 K in PbTiO 3 occurring on few picosecond time scales. Here, we explain the underlying physics of this giant electric field pulse-induced temperature change with the concept of internal energy redistribution: the electric field does work on a ferroelectric crystal and redistributes its internal energy, and the way the kinetic energy is redistributed determines the temperature change and strongly depends on the electric field temporal profile. This concept is supported by our all-atom molecular dynamics simulations of PbTiO 3 and BaTiO 3. Moreover, this internal energy redistribution concept can also be applied to understand electrocaloric effect. We further propose new strategies for inducing giant cooling effect with ultrafast electric field pulse. This Letter offers a general framework to understand electric-field-induced temperature change and highlights the opportunities of electric field engineering for controlled design of fast and efficient coolingmore » technology.« less

Figure 1 Figure 1: Negative EPITC associated with the rhombohedral to orthorhombic phase transition in BaTiO3. (a) Electric field, potential energy, temperature, and polarization vs time. The potential energy of the ground structure at T = 0 K is set as the zero point potential energy. An 80 kV=cm electric field ismore » applied along the (110) direction with T = 101 K. The electric field rises to its steady-state value within 5 ps, rather than instantaneously. This is chosen because, for the negative EPITC, less work (W) and entropy production are preferred. In our MD simulations, the rhombohedral to orthorhombic phase transition occurs at 102 K under zero electric field and at 94 K under an 80 kV/cm electric field. Therefore, at 101 K, BaTiO3 is at its rhombohedral phase under zero electric field and an 80 kV/cm electric field is large enough for triggering a rhombohedral to orthorhombic phase transition. (b) Schematic plot of potential energy vs temperature for the two phases, demonstrating the electric-field-induced phase transition and ultrafast temperature reduction. The solid blue and green lines indicate the potential energies of equilibrated states at different temperatures. The blue and green circles represent the states before and after the application of electric field.« less
