Keywords:heat flow switching device, thermal management, thermal conductivity

In this study, we developed a heat flow switching device using semiconductors characterized by very small thermal conductivity. Its electron thermal conductivity was controlled by the bias voltage. We succeeded in observing 50% increase of heat flow in the capacitor type heat flow switching device.
