Question:
Making use of the energy band structure of silicon estimate the concentration of donors necessary for filling all the equivalent minima of the conduction band near the X point. Would it then be possible for direct e–h recombination at the point to occur? Apply the parabolic approximation of the conduction band and use mde = 0.322m0 for the electron density-of-states effective mass.
