A diode is a device that allows electric current to flow in only one direction, from its anode towards its cathode but not the other way around. There is plenty of online material explaining diode ...

Data diodes are a humble-looking piece of tech, but they are much more important than their appearance might convey. Slowly but surely, they’re becoming an indispensable part of high-security networks ...

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 ...
