Summary

Story summary

Oak Ridge National Laboratory (ORNL), collaborating with The Ohio State University and Amphenol Corporation, developed a method to boost heat flow by applying an electric field to relaxor-based ferroelectric ceramics.
The method enables phonons to travel nearly three times more efficiently in the direction of the field.
The study, published in PRX Energy, reports a thermal conductivity enhancement of close to 300%, surpassing previous methods.
