7.) (Based on Neaman 3.42) - Consider the energy levels shown in the figure. Let T-300K. 1.12 eV E₂ (a) If E₁ - Ep-0.30 eV, determine the probability that an energy state at E-E₁ is occupied by an electron and the probability that an energy state at E- E₂ is empty. Answer: 9.75 x 10-6, 2.0 x 10-14 respectively (b) Answer the same questions as the previous part, assuming Ep-E₂-0.4 eV. Answer: 9.4 x 10-13,2.08 x 10-7 respectively. Energy E₁ -Ey
