WebMar 10, 2014 · A PN junction is the simplest form of the semiconductor diode. In ideal conditions, this PN junction behaves as a short circuit when it is forward biased, and as an open circuit when it is in the reverse biased. The name diode is derived from “di–ode” which means a device that has two electrodes. Both p and n junctions are doped at a 1e15 cm −3 (160 µC/cm 3) doping level, leading to built-in potential of ~0.59 V. Reducing depletion width can be inferred from the shrinking carrier motion across the p–n junction, which as a consequence reduces electrical resistance.
