Let’s say you put n-type and p-type silicon together and then connect a battery, creating a circuit. By joining n-type and p-type silicon together, you create a junction. Now that your pieces of silicon are both positively and negatively doped, you can put them together.This is called p-type or positive-type silicon. ![]() Adding boron to silicon removes electrons from the silicon atom, leaving empty holes where the electrons should be. This is called n-type, or negative-type silicon, because it has more negative electrons than usual. The first is to dope silicon with antimony, which gives it a few extra electrons and allows silicon to conduct electricity.
