Transcript
They're tiny in form, but huge in significance.
Transistors and diodes are semiconductor devices.
The natural materials they are made of are unremarkable – being neither good conductors nor good insulators.
But when these materials are artificially enhanced they become incredibly useful for controlling electric currents.
Diodes
A diode is the simplest semiconductor ...
