    Biasing of P-N Junction01:16

    Biasing of P-N Junction

    The operation of a p-n junction diode involves various biasing conditions, including forward bias, reverse bias, and equilibrium.
    In equilibrium, no external voltage is applied across the p-n junction. The depletion region is formed at the junction interface due to the diffusion of carriers, which leaves behind charged dopants, acceptors on the p-side, and donors on the n-side. These immobile charges create an electric field that prevents further diffusion of carriers. The related energy band...
