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 ...

Quantum metals are metals where quantum effects—behaviors that normally only matter at atomic scales—become powerful enough ...

A p-n junction diode is formed by doping one half of the semiconductor crystal with p-type impurity and the other half with n-type impurity while the crystal is being formed. In reverse bias the diode ...

Many hardware people around these parts will be familiar with devices used as switches, using at least three-terminals to effect this, an input, an output and a gate. Typical devices that spring to ...
