The Drude formula for the de conductivity is given by o = ne-/m. (a) Sketch resistivity, p = 1/0, versus temperature, T, for a typical normal (non- superconducting) metal. Explain the features in your plot. (b) Sketch the Fermi-Dirac function and explain its physical meaning. With a well- drawn, carefully-labelled sketch, a few lines should suffice to explain it. (c) Estimate the probability of an electron to be 0.1 eV above (or below) the Fermi level in a metal at T = 300 K. C= (h = 6.62x10-34J.s; c= 3.0x108 m/s; k= 1.38x10-23 J/K = 8.6x10-5 eV/K; me = 9.1x10-31kg; 1 eV = 1.6x10–19J)
