8c.2. Assuming that dominant carrier scattering is due to acoustic phonons te oc T-3/2 such that the factor . 73/2 is constant in temperature. Show that the energy gap &gap of intrinsic semiconductor is linear with temperature and can be determined from the conductivity o at thermal equilibrium. intrinsic - nopo = n; mobility - o = e(note + PoHn) 3/2 Egap = 2kBT In where C = He(1 + b) 2[mem; ] 13/4 KBT 21h2
