The device dissipates power which generates heat, thus heating the silicon crystal to a temperature of T = °K. Use: m*n = 1.08 m0, m*p = 0.56 m0, Egap = 1.12 eV = Ec with Ev = 0 as the reference, and m0 is the free electron mass = 9.11 x 10-31 kg. Assume Boltzmann statistics applies and do the following: (a) Find the intrinsic Fermi level EFi 2 pts (b) Find the intrinsic carrier concentration ni = pi 2 pts (c) Find EF – Ev 2 pts (d) Find Ec – EF 2 pts (e) Calculate the respective minority carrier concentrations n0 or p0 2 pts
