When looking across the discrete components in your electronic armory, it is easy to overlook the humble diode. After all, one can be forgiven for the conclusion that the everyday version of this c… ...

Researchers have found a way to make a key electronic component on a phenomenally tiny scale -- a single-molecule diode.

Semiconductor diode Method Connect the circuit as shown in the diagram having chosen a suitable protective resistor (between 100 Ω and 500 Ω).
