The heat transistor has an 'off' and an 'on' state. In the 'off' state an energy of e 2 /2 C is needed to add an electron to the island or to take one away (where e is the charge on the electron ...

UCLA researchers have made an electrically-controlled solid-state ‘transistor’ for thermal energy, with a heat-flow on-off ratio of >13:1 when controlled with a ±2.5V base bias at room temperature.

Since a transistor only works because it has a specific, limited amount of electrons running around, high heat could stop a transistor from working altogether. While still working at Bell Labs in ...

Connected to source potential, the top heat spreader is metallic “so for half-bridge topologies the thermal interface material needs to provide electrical isolation to the heatsink” warns the company.
