  1. An n type semiconductor is illuminated by a steady flux of photons with energy greater than the band gap energy. The change in conductivity Δσ obeys which relation?
    [ Here, e is the electron charge, μn electron mobility, μp hole mobility, Δn (Δp) is the excess electron (hole) density ].

    2. A.
    Δσ = 0
    B.
    Δσ = e(σn + σp) Δn
    C.
    Δσ = e(μnΔn - μpΔp)
    D.
    Δσ = e μnΔn
