probability of a state being empty by an electron in the valence band over the range E, - 2kT eV < E E,. The probability that a state at E. + kT is occupied by an electron is equal to the prob- ability that a state at E, level as a function of E. and E. 3.35 kT is empty. Determine the position of the Fermi energy 3.36 Six free electrons exist in a one-dimensional infinite potential well of width a = 12 Å. Determine the Fermi energy level at T = 0 K. 3.37 (a) Five free electrons exist in a three-dimensional infinite potential well with all three 12 Å. Determine the Fermi energy level at T = 0 K. (b) Repeat widths equal to a = part (a) for 13 electrons.
