The Fermi-Dirac distribution for the probability of occupancy versus energy for a system of weakly interacting fermions is given by (E)= exp 1 (E - Ef KBT +1 What is the physical significance of the term EF? Explain with suitable plots the probability of occupancy of energy level E by an electron with (i) E < EF (ii) E = EF and (iii) E > EF In each case, sketch the probability for temperature To = OK ; T > To The Fermi-Dirac distribution for the probability of occupancy versus energy for a system of weakly interacting fermions is given by (E)= exp 1 (E - Ef KBT +1 What is the physical significance of the term EF?
