A pn junction is a semiconductor device that is formed by the joining of two pieces of semiconductor material with opposite types of doping. The two types of doping are n-type and p-type. N-type material has been doped with a donor impurity, such as phosphorus, which gives the material an excess of free electrons. P-type material has been doped with an acceptor impurity, such as boron, which gives the material a deficiency of free electrons.
How does a pn Junction Work?
When a pn junction is formed, the free electrons in the n-type material diffuse across the junction into the p-type material. This creates a region of negative charge in the p-type material and a region of positive charge in the n-type material. The electric field created by this charge separation prevents any further diffusion of electrons across the junction.
