WebJul 5, 2024 · The current in the pn junction diode can only flow from one side to the other. An Ideal pn junction diode is based on the following basic assumption: The diode is in steady state conditions. The doping of the diode is a nondegenerately doped step junction. The diode is 1-D (one dimension). The quasineutral regions are in low-level injection. WebThis article provides a more detailed explanation of p–n diode behavior than is found in the articles p–n junction or diode . A p–n diode is a type of semiconductor diode based upon the p–n junction. The diode conducts current in only one direction, and it is made by joining a p -type semiconducting layer to an n -type semiconducting layer.
