An Electric Field Turns Heat Sideways
Oak Ridge researchers nearly tripled heat flow in one direction by aligning charge and atomic vibrations inside a switchable ceramic.
Summary
Oak Ridge researchers nearly tripled heat flow in one direction by aligning charge and atomic vibrations inside a switchable ceramic.
A team at Oak Ridge National Laboratory, Ohio State, and Amphenol used an electric field to reorganize a ceramic's internal polarization and change how phonons travel. Measurements at the Spallation Neutron Source showed thermal conduction rising by almost threefold along the favored direction. The work points toward switchable cooling components, though device-scale efficiency and durability still need testing.
