3) Assume that the bandgap of a material is 1.42 eV, and that electrons in the material follow Fermi-Dirac distribution. At 300 K, calculate the probability of each of the following cases: a) A state of 0.20 eV above the Fermi energy level will not contain an electron. b) An energy state at E=E₂ is empty c) For part (a), If the energy above the Fermi level is doubled, what does happen for the probability and why? Ep E₁ 1.42 eV E₂
