THIS CONTENT IS PROTECTED AND MAY NOT BE SHARED, UPLOADED, SOLD, OR DISTRIBUTED A pоwer semicоnductоr device consists of а region doped with Boron аtoms such thаt the concentration of holes is p0 = 1.5 x 1017 cm-3. The device dissipates power which generates heat, thus heating the silicon crystal to a temperature of T = 400 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 answer the next questions: a) Find the intrinsic Fermi level EFi [Fermi] in eV b) Find the intrinsic carrier concentration [ni] ni = pi c) Find EF - Ev [EFV] in eV d) Find Ec - EF [ECF] in eV e) Calculate the respective minority carrier concentrations [minority] SELECT CORRECT FROM AVAILABLE ANSWERS
