Diodes come in many shapes and sizes and are used in a wide variety of electronic devices. P-N diodes, the simplest of the diodes, are formed when a semiconductor material is doped with both acceptor and donor impurities. This creates a region in the semiconductor where electrons are majority carriers (n-type) and a region where holes are majority carriers (p-type). The junction between these two regions is called a p-n junction.
How P-N Diodes Work
P-N diodes are biased with a voltage source. When the anode of the voltage source is connected to the p-type region and the cathode is connected to the n-type region, the diode is said to be forward biased. In this mode of operation, electrons in the n-type region are attracted to the anode, and holes in the p-type region are attracted to the cathode. This results in a net flow of charge across the p-n junction, creating an electric current.
When the anode of the voltage source is connected to the n-type region and the cathode is connected to the p-type region, the diode is said to be reverse biased. In this mode of operation, the electric field across the p-n junction is increased, which prevents electrons and holes from crossing the junction. As a result, there is no net flow of charge across the junction, and no current flows.
