Q2: Assume we have sepration between the conduction band and the Fermi energy as Ec – EF = AE =0.2eV. Calculate energy level, E – EF, in the conduction band at which the electron density drops to 1 electron/cm3. Use graphical solution at room - temperature. Assume effective mass is the same as the electron mass at rest m' = mo = 9.11 × 10-31 kg.
