Heat management at the nanoscale has long been a cornerstone of advanced technological applications, ranging from high-performance electronics to quantum computing. Addressing this critical challenge, ...

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 diode is a device that allows current to flow in one direction but not in the other. This ability makes diodes useful in many applications, including converting AC to DC, regulating voltages, and ...

A Josephson diode is the superconducting counterpart of the familiar semiconducting diode — it lets a superconducting current flow forwards, but only a normal current flow backwards — and could enable ...

As active devices go, it doesn’t get much simpler than a diode. Two terminals. Current flows in one direction and not in the other. Simple, right? Well, then there are examples with useful side ...

Robust systems often have several different power sources, and switches are implemented to separate the power supplies from each other to avoid damage. In most cases, multiple diodes are placed in the ...
