When we use an electronic component, we have some idea of what goes on inside it. We know that inside a transistor there’s a little piece of semiconductor with a junction made from differently doped ...

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 ...

A sophisticated halide material can go from diode to non-diode and back depending on the temperature differential across its terminals. How an advanced material can become both p- and n-material based ...
