P-N junction semiconductor diode What is a P-N junction semiconductor diode? A P-N junction diode is a two-terminal or two-electrode semiconductor device, which allows the electric current in only one direction while blocking the electric current in the opposite or reverse direction. If the diode is forward-biased, it allows the electric current to flow. On the other hand, if the diode is reverse-biased, it blocks the electric current flow. A P-N junction semiconductor diode is also called a p-n junction semiconductor device. In n-type semiconductors, free electrons are the majority charge carriers whereas in p-type semiconductors, holes are the majority charge carriers. When the n-type semiconductor is joined with the p-type semiconductor, a P-N junction is formed. The P-N junction, which is formed when the p-type and n-type semiconductors are joined, is called a p-n junction diode. The p-n junction diode is made from the semiconductor materials such as silicon, germanium, and gallium
