Diode is also called crystal diodes, only one direction to the current of electronic components. It is a bonding with a part number of the two terminal devices with in accordance with the direction of the applied voltage, the current flow or the flow of nature. Crystal diode is a p-type semiconductor and n-type semiconductor pn junction formed at the interface of both sides of the formation of space charge layer, and has a self-built electric field. When there is no applied voltage, due to the pn junction on both sides of carrier concentration caused by poor diffusion current and drift current caused by self-built electric field is equal to the power balance.
