What are they?

Semiconductors are solid substances that has a conductivity between that of an insulator and that of most metals, either due to the addition of an impurity or of the temperature effects.

Where can you find them? What are they used for?

You can find most semiconductors in electronics. Semiconductors materials exist in two type - elemental and compound materials. Semiconductors are sort of like silicates, you are probably staring at some right now. You can find them in the computer.Also in tablets, Internet, calculators and many other things. Semiconductors actually changed are lives, the way we communicate. Without the 100 years of research they have made a big difference.
