    for SiliconE_g = 1.1eV \ \  and \ \  N_c=N_v=2 x 10^19 cm^{-3} \ \

    doped with 5 * 10^{16} \  donors \  and \ E_c-E_d=30meV.

    The temperature range is 10K to 600 K.

    Calculate conductivity of silicon.

    conductivity = σ = eμn, assume that μ(T)=constant and


    I am having problem in figuring out what equation to use to find the value conductivity because this problem is different from the one i have in book." alt=" μ_e=1000[\tex]

    (electron mobility is much more than hole mobility,  μ_e=1000[\tex]<br />
