WebIt is important that the photons are absorbed in the depletion region. Thus, it is made as long as possible (say by decreasing the doping in the n type material). The depletion region width in a p-n photodiode is normally 1 – 3 m. The depletion-layer width widens and the junction capacitance drops with reverse voltage across the junction. p n WebA PN junction is the juxtaposition of a n-type and a p-type piece of semiconductor, taken originally from the same block of crystal. The difference between the densities of donors and acceptors N D - N A undergoes a very sharp variation from a negative value in the P region to a positive value in the N region. An abrupt junction is by definition a junction in which …
