    The crystal diode is a pn junction formed by a p-type semiconductor and an n-type semiconductor. A space charge layer is formed on both sides of the interface, and a self-built electric field is built. When there is no applied voltage, the diffusion due to the difference in carrier concentration on the two sides of the pn junction ...
