Keywords:thermal transistor

Thermal transistors that electrically control heat flow have attracted growing attention as thermal management devices and phonon logic circuits. Although several thermal transistors have been demonstrated, the use of liquid electrolytes may limit the application from the viewpoint of reliability or liquid leakage. Here, we demonstrate a solid-state thermal transistor that can electrochemically control the heat flow with an on-to-off ratio of the thermal conductivity (κ) of ~4 without using any liquid.
