Recombination and drift

  1. Dec 16, 2008 #1
    1.what is the link between recombination and drift current for the current flow process in a diode(1.for unbiased condition 2. for biased condition) at equilibrium. i have the feeling that both are same as i read that diffusion compensates drift at some places and at other places, diffusion compensates recombination. i want to know the exact difference between the current contributed by drift and that contributed by recombination and how they sum up to the diode current.

    2.how can we view drift current and diffusion current in a band diagram of a diode.(both biased and unbiased.)?
