Given the Fermi energy, EF for copper at T = 0 K is 7.00 eV and the electrons in copper follow the Fermi-Dirac distribution function. Using Fermi -Dirac equation, show that the probability of an energy level at 7.15 eV being occupied by an electron at T = 0 K is different as compared at T = 300 K. Illustrate the probability of occupation of energy levels by electrons at T =0 K and at T = 300 K using well labelled diagram. Given Boltzmann constant, KB = 8.617 x10-5 eV/K).
