This Design Idea describes a method by which you can detect and assess air or liquid fluid flow using an externally heated semiconductor diode. Airflow across the heated diode reduces its temperature, ...

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 ...

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 ...

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 ...

Diodes let electricity flow in only one direction, helping circuits work safely and correctly. This video shows how they do ...
