    Find the number densities of n-carriers

    Homework Statement In silicon, Eg = 1.12 eV and the effective mass of the n-carriers is m* = 0.31me, where me is the electron mass. Find the number densities of n-carriers at 100 K and at 250 K. Homework Equations square root of (NcNv)*e^(-Eg/kt) The Attempt at a Solution...
