An n type silicon sample with donor doping concentration of ND = 1017/cm3 is steadily illuminated such that there is an additional generation rate (g') of 1020 cm-3s-1. If τn0 = τp0 = 10-6 s, the portion of qnari-fermi level for holes with respect to intrinsic level is ______ eV. (ni = 1010/cm3 and τ = 300 K)
    Correct answer is between '-0.3,-0.2'. Can you explain this answer?

    The recombination rate (R) is 1019 cm-3s-1, we can calculate the excess minority carrier density (δn) using the equation:

    δn = (g - R) / (μn + τn)

    where μn is the electron mobility and τn is the electron lifetime.

    Assuming typical values for n-type silicon, we can use μn = 1350 cm2/Vs and τn = 1 μs (10-6 s).

    Plugging in the values, we get:

    δn = (1020 - 1019) / (1350 + 10-6)

    Simplifying, we have:

    δn = 101 / 1350

    Calculating, we find:

    δn ≈ 0.075 cm-3

    Therefore, the excess minority carrier density is approximately 0.075 cm-3.
