A diode is a semiconductor device that allows electrical current to flow in one direction while blocking it in the other.

We’re all familiar with semiconductor diodes, whose function is to allow electricity to easily flow in one direction and impede its progress in the other. A thermal diode performs a similar gating ...

New thermal diode technology could steer heat one way, preventing overheating and prolonging battery life in phones and other devices.

Engineers have long known how to steer electricity in one direction, but heat has been far harder to tame. Now a new one-way thermal “diode” promises to give designers similar control over heat flow, ...

How a Virginia Tech research team constructed its novel thermal diode. Test results of the thermal diode. Electrical engineers are obviously very familiar and comfortable with the basic diode, a ...

A model of a quantum thermal diode based on a qubit and qutrit. The asymmetric design allows this system to behave as a thermal diode when connected between two thermal baths. Credit: APL Quantum ...

Reverse polarity is one of the most common causes of circuit failure, from hobby projects to industrial systems. The good news is that a well-designed reverse polarity protection using MOSFET ...
