We've now learned about Doping Semiconductors, and how mixing some chemicals into
a semiconductor can turn it into a conductor.

Doped semiconductors can be used to make something called a diode.

A diode is something that you can put electricity through, but it only goes in one direction.
Kind of like pouring water down hill, it can't flow back up.

If you look on a circuit board you will see all sorts of diodes.
They are a very important part of how things like computers work!
