(a) [1 point] – Under equilibrium conditions and , what is the probability of an electron state being occupied if it is located at the Fermi level? The probability of electrons occupying states at a given energy under equilibrium conditions is given by the Fermi function. Here we are told the energy of interest is . Thus ( ) ( ) (b) [1 point] – If is positioned at , determine (numerical answer required) the probability of finding the electrons in states at . The d...
